I am trying to copy a selected folder to a defined target.
function importLabs(selected) {
if(selected = "labAuto") {
//Open Folder dialog box
var myLab=Folder.selectDialog("Import");
myLab.copy ("~/Desktop/In here");
}
}
Can't figure this one out. Am I using the wrong function .copy()?
Unfortunately there is no copy method for Folder.
You will need to create your destination folder first then copy each file.
If you would like to copy sub-folders as well then you need to do it recursively.

I have multiple folders in a single directory and each folder(folder name as per Siteid) contains the .orig file. so I want to copy the latest file created ".orig" file from multiple directories into a single directory.
The file received from ftp in each directory on a weekly basis
Filename format
:PSAN{SiteId}_20190312_TO_20190318_AT_201903191600.txt
I tried to copy a file using windows command
for /R "source" %f in (*.orig) do copy %f "destination"
using this command I able to copy an all .orig file from multiple folders into a single folder but it fetches all file.
can we do modification in command to fetch the latest file?
How to perform this task using an SSIS package or using cmd.
Create two package variables called InputFileNameWithPath and OutputFolderPath. The Former will be dynamically set in the package. The former should be hardcoded to your destination folder name.
Create a ForEachLoop enumerator of type File Enumerator. Set the path to the root folder and select the check box for traverse sub-folders. You may want to add an expression for the FileMask and set it to *.orig that way only the .orig files are moved (assuming there are other files in the directory that you do not want to move) Assign the fully qualified path to the package variable InputFileName.
Then add a System File Task into the ForEachLoop enumerator and have it move the file. from the InputFileNameWithPath to the OutputFolderPath.
You can use a Script Task to achieve that, you can simply store the folders within an array, loop over these folders get the latest file created and copy it to the destination directory (you can achieve this without SSIS), as example:
using System.Linq;
string[] sourcefolders = new string[] { #"C:\New Folder1", #"C:\New Folder2" };
string destinationfolder = #"D:\Destination";
foreach (string srcFolder in sourcefolders)
{
string latestfile = System.IO.Directory.GetFiles(srcFolder, "*.orig").OrderByDescending(x => System.IO.File.GetLastWriteTime(x)).FirstOrDefault();
if (!String.IsNullOrWhiteSpace(latestfile))
{
System.IO.File.Copy(latestfile, System.IO.Path.Combine(destinationfolder, System.IO.Path.GetFileName(latestfile)));
}
}
An example C# Script Task for this is below. This uses SSIS variables for the source and destination folders, and make sure to add these in the ReadOnlyVariables field if that's how you're storing them. Be sure that you have the references listed below as well. As noted below, if a file with the same name exists it will be overwritten to avoid such an error, however I'd recommend confirming that this meets your requirements. The third parameter of File.Copy controls this, and can be omitted as it's not a required parameter.
using System.Linq;
using System.IO;
using System.Collections.Generic;
string sourceFolder = Dts.Variables["User::SourceDirectory"].Value.ToString();
string destinationFolder = Dts.Variables["User::DestinationDirectory"].Value.ToString();
Dictionary<string, string> files = new Dictionary<string, string>();
DirectoryInfo sourceDirectoryInfo = new DirectoryInfo(sourceFolder);
foreach (DirectoryInfo di in sourceDirectoryInfo.EnumerateDirectories())
{
//get most recently created .orig file
FileInfo fi = di.EnumerateFiles().Where(e => e.Extension == ".orig")
.OrderByDescending(f => f.CreationTime).First();
//add the full file path (FullName) as the key
//and the name only (Name) as the value
files.Add(fi.FullName, fi.Name);
}
foreach (var v in files)
{
//copy using key (full path) to destination folder
//by combining destination folder path with the file name
//true- overwrite file if file by same name exists
File.Copy(v.Key, destinationFolder + v.Value, true);
}
I will move certain files. how to move the image file from directory to another directory,
example file img.jpg from /storage/emulated/0/Myfolder to /storage/emulated/0/Urfolder?
File.rename works only if source file and destination path are on the same file system, otherwise you will get a FileSystemException (OS Error: Cross-device link, errno = 18). Therefore it should be used for moving a file only if you are sure that the source file and the destination path are on the same file system.
For example when trying to move a file under the folder /storage/emulated/0/Android/data/ to a new path under the folder /data/user/0/com.my.app/cache/ will fail to FileSystemException.
Here is a small utility function for moving a file safely:
Future<File> moveFile(File sourceFile, String newPath) async {
try {
// prefer using rename as it is probably faster
return await sourceFile.rename(newPath);
} on FileSystemException catch (e) {
// if rename fails, copy the source file and then delete it
final newFile = await sourceFile.copy(newPath);
await sourceFile.delete();
return newFile;
}
}
await File('/storage/emulated/0/Myfolder').rename('/storage/emulated/0/Urfolder')
If the files are on different file systems you need to create a new destination file, read the source file and write the content into the destination file, then delete the source file.
I am writing a gradle script to delete files and folder which are not used by other resources inside the 'Temp' folder in Windows i.e %TEMP%'. However, if some files are used by another resources, then it will not delete and throw exception when I try to delete. I tried:
task cleanTempFile(type: Delete) {
def directoryPath = "/path/to/temp/folder.."
file(directoryPath).deleteDir();
}
This will actually work as expected (not delete used ones but delete the ones that are not used by any resources). However, the problem is that it deletes the 'Temp' folder itself. I want to KEEP the Temp folder but delete contents inside of it. I tried :
task cleanTempFile(type: Delete) {
//delete files
delete fileTree(dir: 'path/to/temp/folder' , include: '**/*.*')
//deletes folder
file( directoryPath ).list().each{
a -> delete "path/to/temp/folder/${a}"
}
}
but it gives me error saying unable to delete the file. It does not work if any of the files and folder are used by other resources (e.g open a file and try to delete the folder, unopened or unused are not deleted). Is there any way I can achieve this? I appreciate any help or suggestion. Thank you.
I am looking for a way to add File(s) to an existing directory that has a random name as part of a Visual Studio Setup Project and I hoped someone might be able to help me solve this puzzle please.
I have been attempting to obtain the discovered path property of the directory using a Launch Condition; Unfortunately this method returns the full file path including the filename, which cannot be used as a directory property.
The directory in question takes the form [AppDataFolder]Company\Product\aaaaaaaaaaaa\
where aaaaaaaaaaaa is a random installation string.
Within the Launch Condition Setup I check for the directory's existence by searching for a file that would appear inside it,
Search Target Machine
(Name): File marker
Filename: sample.txt
Folder: [AppDataFolder]Company\Product\
Property: DIRFILE
Launch Condition
(Name): File marker exists
Condition: DIRFILE
In the Setup Project I add the file I wish to insert, with the details
Condition: DIRFILE
Folder: 'Installation folder'
Then in File System Setup I add a new folder entry for the random directory aaaaaaaaaaaa
(Name): Installation folder
Condition: DIRFILE
DefaultLocation: [DIRFILE]\..\ *Incorrect*
Property [DIRLOCATION]
As you can see the installer detects the existence of the marker file but, instead of placing my file at the same location, when using [DIRFILE] the installer would incorrectly try and insert it INTO the file;
This is because the file path was returned
[AppDataFolder]Company\Product\aaaaaaaaaaaa\sample.txt
where I instead need the directory path
[AppDataFolder]Company\Product\aaaaaaaaaaaa
Therefore I was wondering if it was possible to return the directory the file was found in from Search Target Machine (as opposed to the file location of the file), if I could extract the directory path by performing a string replace of the filename on the file location DIRFILE within the DefaultLocation field in File System Setup, or if perhaps there is even another method I am missing?
I'm also very interested in a simple solution for this, inside the setup project.
The way I did solve it was to install the files to a temporary location and then copy them to the final location in an AfterInstall event handler. Not a very elegant solution! Since it no longer care about the user selected target path I removed that dialog. Also I needed to take special care when uninstalling.
public override void OnAfterInstall(IDictionary savedState)
{
base.OnAfterInstall(savedState);
// Get original file folder
string originDir = Context.Parameters["targetdir"];
// Get new file folder based on the dir of sample.txt
string newDir = Path.GetDirectoryName(Context.Parameters["dirfile"]);
// Application executable file name
// (or loop for all files on the path instead)
string filename = "ApplicationName.exe";
// Move or copy the file
File.Move(Path.Combine(originDir, filename), Path.Combine(newDir, filename)));
}
I'm trying to save a file in a folder other than the extensions folder. Right now I'm using:
var file = Components.classes["#mozilla.org/file/directory_service;1"].
getService(Components.interfaces.nsIProperties).
get("ProfD", Components.interfaces.nsIFile);
if( !file.exists() || !file.isDirectory() ) { // if it doesn't exist, create
file.create(Components.interfaces.nsIFile.DIRECTORY_TYPE, 0777);
}
this.f = file.path+"\\text.txt";
How can I change the file path so that it saves it somewhere else on the machine? Or is this not possible?
Thanks!
You can use different "special folder" keys too. For a list of some common ones, see:
https://developer.mozilla.org/en/Code_snippets/File_I%2F%2FO#Getting_special_files
You can also initialize a file with any absolute path. See:
https://developer.mozilla.org/en/Code_snippets/File_I%2F%2FO#Creating_an_.0ansIFile.0a_object_%28.22opening.22_files%29
