Visual Studio: Add existing folder(s) to project - visual-studio

Is there a way to add existing Folders to a Visual Studio Project so that I do not have to do this file by file?
Edit
To make it clear: I want to add references not copies.

If the folder and its contents have already been created and it physically exists under the Project, you can click the Show All Files icon (at the top of the Solution Explorer windows) and then when the folder shows as a dotted icon, right-click it and choose Include In Project and the folder and all its contents are added.

VS 2019
Click on the 'Show All Files' icon at the top of Solution Explorer window.
Then the folders/files of the selected project will be displayed as dotted icons. You can right click any of them and select include in project to include them in the project.
For solution folders, click the 'Show All Files' icon then first exclude the desired folders/files and then include them.

You could open Add Existing Item dialog, select a bunch of files, click on Add's button drop-down menu and choose Add as a link. It will add files as references and won't copy them.

You can drag and drop the entire folder. If all files don't show you can repeat the drag'n'drop procedure for subfolders.

#Mark s answer is good, but if there are hundreds or thousands of files it will be quite cumbersome to add all of them. Plus, it does not provision for new files.
There is another method using the .csproj file. I have used this to add content that is part of a submodule that does not have a .csproj file of its own.
Note that I have used the <Content /> tag, as I did not need any of the linked content during compilation.
<ItemGroup>
<Content Include="..\my\submodule\directory\**" Link="Directory\In\Main\Project\%(RecursiveDir)%(Filename)%(Extension)" />
</ItemGroup>

This answer applies to visual-studio-2012 and visual-studio-2013, the most up to date versions at the time the question was asked and this answer was given. More recent versions have improved their handling and have other answers here. For someone using the old versions, this answer still applies.
Answer:
I don't think there is, but if you have all the files in one folder, you can add multiple files in one go. Just mark them all in the add file dialog.

right click the project, and choose "New Solution Explorer view", a window pops up.
and then form the toolbar of the new window ("solution explore window"), you click the "Show All Files" icon.
then include the folders of interest into your project...

If you're working in VS 2019 Community Edition, I find that you can:
Open the parent folder of whatever folder you're trying to add in windows explorer
Right-click and copy that folder
Go to the solution explorer in visual studio
Right-click then paste the folder wherever you want to in the solution tree

In Visual Studio 2019 I could not drag and drop from file explorer or 'Show All Files' and then add them. Instead, while in File Explorer, right click and choose copy, then click on the location within Visual Studio 2019 and right click and choose paste. All of the files in the folder and subfolders will be added.

kburnik's answer worked well for my use-case, but for anyone who needs a scriptable way to bring a lot of folder hierarchy back, you can modify the .*proj file to re-include the folders and files:
<?xml version="1.0" encoding="utf-8"?>
<Project ...>
...
<ItemGroup>
<Compile Include="Path\To\File1.ext" />
<Compile Include="Path\To\File2.ext" />
...
</ItemGroup>
<ItemGroup>
<Folder Include="Only\Empty\Folders\Need\To\Be\Listed\Here" />
...
</ItemGroup>
Just make sure that before you do this, you save the .*proj file if it's still open in Visual Studio.

You can drag and drop the entire folder or missing folders in the project.

If the folder and its contents have already been created and it physically exists under the Project then click on view over the project then you can see all folders and files and you just need to copy files and click on solution in the same folder view and paste all in there

It has been a while since this was originally posted, but here is an alternative answer for a solution folder that is NOT inside of a project. If you only care to be able to look at the physical files from inside visual studio and do not necessarily require to see them in the solution explorer default view, then click on the switch view button and choose the folder view and any physical directory/directories that are under your solution root folder will appear here even if they do not appear in the solution explorer default view.
If however, you want to add a folder tree that isn't too large as a virtual solution directory/directories to match your existing tree structure, do that and and then "add the existing" physical files to the virtual directory/directories. If the physical directory exists in your solution directory it will not copy the files - it will link directly to the physical files but they will appear as part of the solution virtual directories.

Possibly some of you weren't born when this question was first asked!
If you have external directories, you can add them to a solution as a "website". This gives you all the benefits of being able to search through the solution and easily add new files to the website. It doesn't have to contain html, it can be a set of word documents, for example.
So for example, I've got a single solution that contains every sql and oracle query I've ever worked on or harvested from a co-worker. Why? Because it's difficult to keep up with similar sounding field and table names across different databases when you're trying to write a new query.
This also works with TFS.

Check whether that folder is inside project folder or not, if yes:
click Show All files in solution explorer.
now you can see folder name in solution explorer. right click the folder -> Include In Project.
If the folder out of project please copy it into the project directory in the place where we want it.

If your folder exist in another project but you want to add the folder and its content to another project just
-- go to the folder location
-- Copy your desired folder
-- go back to your current project
-- right click on the project and then just paste it.
folder will be added in your current project.
you may need to fix the namspace of the copying file.

You can use the following extension to add a solution folder, which is going to have the same name and the same content as the existing one without it being moved in the file system at all.

Just drag and drop the folder in solution explorer.

In visual studio 2015, solution folder leads to a unsupported error [duplicate]

I have a Visual Studio Solution. Currently, it is an empty solution (=no projects) and I have added a few solution folders.
Solution Folders only seem to be "virtual folders", because they are not really created in the Filesystem and files inside solution folders are just sitting in the same folder as the .sln file.
Is there a setting that i've overlooked that tells Visual Studio to treat Solution Folders as "real" folders, that is to create them in the file system and move files into it when I move them inside the solution into one of those folders?
Edit: Thanks. Going to make a suggestion for VS2010 then :)
There is a workaround, that actually behaves as expected.
Add a New or Existing Web Site to the Solution. (I usually create a new one.)
Just make sure it's created inside your solution folder. (I sometimes even create a "link" to an external folder, e.g. 'Docs' or 'Marketing' on a network share. In that case it's ignored by Git of course.)
Make sure to go to the "Project" settings or Configuration Manager to exclude this "Web Site" from Build and Deploy!
Done. Now Solution Explorer will reflect any change in the file system and vice versa (including subfolders).
I (miss)use it for specs, docs, PM and some DevOps scripts that are shared within the team. It's easy to choose, what to include in source control or not, and (if set up correctly) it doesn't conflict with build.
I know the feature is not intended for that use case, but except for the maybe misleading "Project" icon I didn't find any shortages to that hack yet. And there still are use cases where the classical (virtual) Solution Folders that VS provides, fit in the picture. What do you think?
No special setting. I don't think it's supported.
You can create real folders in a "project" within the solution, but not in the solution itself.
In Visual Studio 2017, click on the "Solutions and Folders" icon in the Solution Explorer window. This button toggles from the virtual "solution" view into a "source view" that matches the layout of folders and files on the file system. When you add a new folder, the folder is physically created in the expected location.
.
The chosen answer suggests it would be possible to use actual projects instead of solution folders, but does not really explain how. I guess what I'm describing here is possibly the least awkward way of achieving that... :-P
The problem with regular project files is that they eventually will be compiled by MSBUILD. And if you want have a project which only contains non-compilable files, that will be an issue.
But some time ago Visual Studio introduced a new project type: Shared Project (.shproj extension). This project type does not get compiled by default, but only when (and only if) it is referenced by another project.
So one part of the trick here is to use shared projects instead of solution folders. It's obviously possible to add a shared project that is never referenced by any other project, meaning we can avoid the issue presented above.
Then, by using <None Include="**/*" /> clause in the .shproj file, we can make it automatically reflect any new files and/or subfolders.
So basically do this:
Create a new folder in your solution.
Add a new .shproj file at the root of this new folder.
Reference the new .shproj in your solution.
For instance, in my case, I've created a DockerDev.shproj, so I can group some docker-related scripts that we run only in our development machines:
<?xml version="1.0" encoding="utf-8"?>
<!-- DockerDev/DockerDev.shproj -->
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<None Include="**/*" />
</ItemGroup>
</Project>
This .shproj file will keep track of any file, in any subfolder of this new DockerDev folder in my solution.
As far as I could see, this solution works pretty much like what the OP requested: it will work as a non-compilable reference to a folder, and it will automatically reflect any changes made to it.
Sara Ford contributed a Macro to add do this. In Visual Studio 2010, if you open your Macro Explorer, you will see a macro called "GenerateSlnFolderOnDirStructure." This will automate the creation of the Solution Folders and add the files.

Remove the hassle of adding several files to solution folder. Just use the context menu for the solution and just below the option of creating a new solution folder you now find 'Add Folder as Solution Folder'. This will create a solution folder with the same name as you selected and add the items inside of that folder to the solution folder. This will not move the files on disk.
You can just sync your new solution folder nesting level and also name with the actual filesystem folder and it works like a charm!
Existing project :
Create the actual folder
Create the solution folder with the exact same name
Copy your project folder into the new folder (Actual file system)
(in solution explorer) - Righ-click on same folder
Add => Existing project
Add new project :
Create your solution folders
(Right-click on solution) => Add new project
Change the Location address under the project name you want to add, to the exact same address in your solution folders
No, it's not supported. As you suspected, solution folders are simply virtual subentries in the .sln file, nothing to do with the file system.
For C# in Visual Studio 2019 I used this way (Seems to be similar to this answer, but that didn't work at least in C# solutions)
In solution explorer click on switch views
Choose folder view
You can add individual folders to the solution
To get back to the regular view of solution explorer just click switch views again and choose the solution.
There seems to be a limitation using this way (comment from #montonero):
... just open a solution with multiple projects and try to move the projects to some other real folders through the folder view. The issue is VS doesn't update paths to projects in a solution file
Visual studio has no support for this. I made an extension that does something similar for VS2013 though. It maps solution folders to physical folders on your hard drive, though the mapping is one way (from hard drive to solution). That means a solution folder's contents will reflect the hard drive folder's contents, and not the other way.
With that out of the way, the extension may still be useful.
It has support for mapping solution folders to physical folders, filtering files and directories based on regex, and remembering mappings in your .sln file. Properties are non-intrusive so developers without the extension can still open the sln and not be affected.

Create "Solution folder". This will create logical folder, but not physical one.
Right click to the solution folder and open a new project dialog. But before you click OK, you have to change a project location to your desired physical folder and VS will create it and place the project inside.
Create an empty solution then
open .sln file in an editor
and put these lines of code after MinimumVisualStudioVersion
Project("{2150E333-8FDC-42A3-9474-1A3956D46DE8}") = "src", "src", "{9D8C3BB1-AEDB-4757-8559-995D12A4E6D0}"
open the solution in vs and you should add the same folder to it
now you can see the folder and add a project to it
you have a real folder in windows and a virtual one in vs
be sure that you
created the projects with that path
You can add real folders by choosing "Add new filter" for a Visual Studio project file. You can also do "Add new filter" under an existing folder. Once the folder is created, rename it and add source or header file or whichever suits your project. This is one way I know which lets us create real folders through the Visual Studio IDE.
I've wanted this feature a few times myself, but at the end of the day, you really do NOT want the ability to do this. Think of your Solution (file) as as the root of a web application and think of Solution folders as Virtual Directories (literally and functionally). The contents of a web virtual directory could be physically on a different server altogether. Where Visual Studio muddled up the solution folders concept is by allowing you to create new files inside the folder. You should always "Add Existing" when adding content. When you add existing, it creates a link to the source location of the file.
But as for the reason you do not want solution folders to behave like "physical" folders is because your solution layout may not necessarily use the same convention as your source control layout. Solution folders allow you to customize the hierarchy of your projects so that you can group projects and items together any way you like, and then decide you don't like it and change it again without having to go through the nightmare of moving source control items around and irritating the rest of your team.
Note: Yes this is possible you can create a folder on root but its lil bit tricky....
By giving some extra efforts you can do it How?
Lets follow the step--
1-Create Folder eg: "newfolder" on root (where your .sln file reside).
2.Copy and paste your projects inside the folder.
3.go to your sln file and find moved projects and append newfolder\ in moved project's address.
4.Save sln file.
5.Open your project and Commit the repository in git or so...
6.Take the repository on fresh location.
YOU are done...
if still you are not able to see your folder -----
1.Add a solution folder xyz.
2.Open sln file and change that folder name with your folder name.
Congrats you are done..
If you face any problem just write me for help..
The folder created underneath the solution will be virtual as said. Maybe this might be called a workaround but you can physically create the folder on disk either before or when you add new item/project and Robert should be a sibling of your dad.
ps- on closer look maybe i should explain "bob's your uncle" means your fine/sorted.
I have a bit of a workaround for this (it's not great, but it works).
Create a folder in your solution (i.e. "Contoso")
Right click on the solution and then click "Open Folder in Solution Explorer"
Create the physical folder (i.e. "Contoso") in the solution directory
Copy/Create files in the physical folder.
Drag the files into the virtual folder in the solution explorer.
It's not great because you will need to manually maintain the file references, but it works for me.
Yes, it is possible in Visual Studio 2019 for the project
Though this is an old topic, I will add my answer, because I had the same issue and searched for a solution but it seemed that everyone is 100% sure that there is no way to do it. So I started to experiment with VS 2019, tried a lot of settings, and eventually figured the way out.
1 Button :D
You only need to click 1 button - Show All Files, and you will see the physical structure of your Visual Studio Solution:
Now you can add files and folders to the project and they will be added to the file system (physically)
Right-click on your project → Add → New Folder
Note that the option changed from New Filter to New Folder
My recommendation for C++
Create a root folder inside your project's directory which will contain all the application related stuff (code, headers, data, libs... ). I name it Project
Add subfolders as you'd like to structure your code. I prefer the following layout: include, src, data, libs, etc
Now setup Visual Studio to recognize these folders as headers and sources directories.
Click on your project in the Solution Explorer. Note, in my case, it is CrazyDemo, not the Solution 'CreazyDemo' (1 of 1 project)
Go to the project properties menu: Project→Properties
Open Configuration Properties→VC++ Directories tab
Edit Include Directories and set to $(ProjectDir)/Project/include;$(IncludePath)
Edit Library Directories and set to $(ProjectDir)/Project/libs;$(LibraryPath)
Edit Source Directories and set to $(ProjectDir)/Project/src;$(SourcePath)
You may use the Scope to This option if you want to focus on 1 project. Just right-click on the Project folder and press Scope to This
Note that after this action, in order to open Project Properties you need to click on any of your project files (like main.cpp in the example) and then click on the editable client area (like when you want to change the code) and only after that you'll be able to see the Project→CrazyDemo Properties option. [Visual Studio is Insane 🤦‍♂️]
Finally, you may have a project like this

On add existing item in VS2010, why can't I "add as link" a file from the same project?

I have two folders in my library project, folder A and folder B. Folder A will contain all the real files, but Folder B (and a bunch of other folders) need to contain links to the folder A files.
I tried going Add existing item (go to folder A)-> add (down arrow) -> add as link but the add existing item dialog window just closes and nothing happens. It seems I can add links to files outside the library project though. What's going on here?
-Isaac
For some reason Visual Studio seems to silently ignore possible problems with adding file as a link. I just had the same problem and the solution was to:
Check if project folder already contains a file with the name of file being linked, if so delete or rename this resource.
Visual Studio 2010 seems to cache project directory contents, as (1) was not enough to successfully link the file. Restarting VS helps.
Sound like Visual Studio is crashing for some reason. I just tested this in project that has many folders. I had an images folder and I was able to add as link and image to another folder, so it seems it is possible.
It does add the file to the project but does so to the original location, not the new location.
You can see this if you exclude the original file from your VS project (but don't delete the file from disk) - the file will then get add to your project in it's original location
e.g. if you have folder FolderA\index.htm and FolderB, and you want to create a link to index.htm in FolderB. Exclude index.htm from your project (but leave it in FolderA on the disk) so your project just has two empty folders. Right-click on FolderB and click Add Existing Item, select index.htm from FolderA and click Add as Link. The file will be added to your project but under FolderA (where it resides on disk) not within FolderB which is where you told it to add it.
So looks like a VS bug to me.
As has been mentioned, this is a valid scenario if you have multiple "root" websites within one project but you want to share resources between them
In my case (using Visual Studio 2013) I just had to show all files (button on the top of the Solution Explorer), right click on each file/folder and click on "Include on Project".

Visual Studio - how to BULK add files under a given directory as LINK?

How can one add in Visual Studio all the files under a given directory 'as link' (that is, without Visual Studio creating a local copy under current project's directory, which is what happens if one adds a folder as 'existing item')?
In my case, I don't want local copies. Instead, I want to work with existing items in their original locations. And, I don't want to add them by going through each folder. Instead, I want to specify a given folder and click a magic silver bullet button that adds all of the files below it as 'link'.
Thanks in advance.
(Disclaimer - I went through related questions, but all of them result in VS creating local copies.)
For single files
on the add item dialog you can see a small arrow pointing down on the add button
click that (since it is a button with a dropdown) and chose the add as a link menuitem. that will add the item as link
For multiple files
on the add existing items dialog SELECT all the files you want to add as an link and press the menu item ont he add button add as a link
For Multiple files in multiple locations
If you want to select a folder and add all the items on all subfolders then you can do that this way,
on the open dialog do a search for file types you want to add, select them all and do the "add item as link" action.
Since your question changed twice including the change on the title (once)
Visual Studio - how to BULK add files under a given directory as LINK?
edited title
I have added all the things i think you needs let me know if you still like to do something else
Hope this helps
Dan
If you want files under an external directory to be synced automatically in your Visual Studio project (i.e any new files are added to the solution explorer and any deleted ones are removed) then you can specify a wild card in the link. Do to this you will need to edit the project file (.csproj, .vbproj) manually though.
Find the section in the file where the ItemGroup elements are located and add something like this:
<ItemGroup>
<Content Include="..\MyDirectory\*.*" />
</ItemGroup>
This will add all files under MyDirectory (one level up from the project) to the solution automatically.
If you select 'Show all Files' in the Solution Explorer, you can than view all the files and folers and select them and right click to add them using 'Include in Project'.

Note: Yes this is possible you can create a folder on root but its lil bit tricky....
By giving some extra efforts you can do it How?
Lets follow the step--
1-Create Folder eg: "newfolder" on root (where your .sln file reside).
2.Copy and paste your projects inside the folder.
3.go to your sln file and find moved projects and append newfolder\ in moved project's address.
4.Save sln file.
5.Open your project and Commit the repository in git or so...
6.Take the repository on fresh location.
YOU are done...
if still you are not able to see your folder -----
1.Add a solution folder xyz.
2.Open sln file and change that folder name with your folder name.
Congrats you are done..
If you face any problem just write me for help..
The folder created underneath the solution will be virtual as said. Maybe this might be called a workaround but you can physically create the folder on disk either before or when you add new item/project and Robert should be a sibling of your dad.
ps- on closer look maybe i should explain "bob's your uncle" means your fine/sorted.
I have a bit of a workaround for this (it's not great, but it works).
Create a folder in your solution (i.e. "Contoso")
Right click on the solution and then click "Open Folder in Solution Explorer"
Create the physical folder (i.e. "Contoso") in the solution directory
Copy/Create files in the physical folder.
Drag the files into the virtual folder in the solution explorer.
It's not great because you will need to manually maintain the file references, but it works for me.
Yes, it is possible in Visual Studio 2019 for the project
Though this is an old topic, I will add my answer, because I had the same issue and searched for a solution but it seemed that everyone is 100% sure that there is no way to do it. So I started to experiment with VS 2019, tried a lot of settings, and eventually figured the way out.
1 Button :D
You only need to click 1 button - Show All Files, and you will see the physical structure of your Visual Studio Solution:
Now you can add files and folders to the project and they will be added to the file system (physically)
Right-click on your project → Add → New Folder
Note that the option changed from New Filter to New Folder
My recommendation for C++
Create a root folder inside your project's directory which will contain all the application related stuff (code, headers, data, libs... ). I name it Project
Add subfolders as you'd like to structure your code. I prefer the following layout: include, src, data, libs, etc
Now setup Visual Studio to recognize these folders as headers and sources directories.
Click on your project in the Solution Explorer. Note, in my case, it is CrazyDemo, not the Solution 'CreazyDemo' (1 of 1 project)
Go to the project properties menu: Project→Properties
Open Configuration Properties→VC++ Directories tab
Edit Include Directories and set to $(ProjectDir)/Project/include;$(IncludePath)
Edit Library Directories and set to $(ProjectDir)/Project/libs;$(LibraryPath)
Edit Source Directories and set to $(ProjectDir)/Project/src;$(SourcePath)
You may use the Scope to This option if you want to focus on 1 project. Just right-click on the Project folder and press Scope to This
Note that after this action, in order to open Project Properties you need to click on any of your project files (like main.cpp in the example) and then click on the editable client area (like when you want to change the code) and only after that you'll be able to see the Project→CrazyDemo Properties option. [Visual Studio is Insane 🤦‍♂️]
Finally, you may have a project like this

Visual Studio solution that just points to a folder and shows all sub-folders and files in the solution explorer?

Is there a way to create a blank solution, or some type of file-based project solution within Visual Studio so that I can point to a root folder, and have all of the sub-folders and files in that root, show up in my solution explorer? I realize I can create a blank solution and then add the individual items manually by add > existing item, however, this does not keep the folder structure intact, and, well, it would take forever if I have a lot of folders/files.
You can also create the blank solution and then click the second-from-the-right icon at the top of the solution explorer (it looks like three files with one "cut out"). Once you click that button to show the files in the solution directory that are not in a project, you can select all the files (with shift-click) and then right-click on your selection and select "Include In Project."
Also note you can select multiple files in the "Add Existing..." file window with shift- or control-click.
You have to create a Visual Studio Project inside your solution to be able to add files with keeping their folder structure. The files to be added must reside below the project's main folder.
I suggest adding a "C# Empty Project" (Solution Explorer: Solution > Add > New Project ... > Visual C# > Windows > Empty Project). After that you can proceed as described by SoloBold to show the files in the project folder. Right click on the topmost folder of your source files an select "Include In Project" and the whole folder structure including all files will be added. This may take some time depending on the number of files / subfolders.
