I appreciate any help that can be given on this issue. So, to keep things simple lets just say I have a 3rd party program and in order for it to work properly now, I have to modify a folder so Users have Full Control and I also have to remove the Deny permissions that is present for Users. Doing this manually is a pain as there are about 5 folders that have to be modified, and multiple computers per location.
I currently use the following in my .bat files to grant users or domain users full control.
Icacls "C:\Program Files (x86)\testbatfiles" /grant:r "Users":(OI)(CI)F
I read that I can use /remove:d to remove deny permissions and their example had /remove:d /grant:r thus, I modify my bat file to be this,
Icacls "C:\Program Files (x86)\testbatfiles" /remove:d /grant:r "Users":(OI)(CI)F
However, if I try to run this bat file with this new /remove:d it does not work. I noticed that if I just keep the original /grant:r line and add a new Icacls line with /remove:d that seems to work.
My question is, can I remove deny permissions while granting users rights in the same command? If so, how?
The computers here at our branches are Windows 10 32bit.
Thanks,
Sean R
Here's your one-liner.
icacls "C:\Program Files (x86)\testbatfiles" /remove:d "Users" /grant:r "Users":(OI)(CI)F /T
I ran and verified this command on my Windows 8 machine.
I removed the deny permissions first with /remove:d "Users". The remove switch does not require the (OI)(CI) parameters. It simply removes all denied permissions for that user.
Then I processed the /grant:r "Users:(OI)(CI)F /T to give the user full control. The /T passes those permissions to all files and directories in the subfolders. You can remove that if you don't want the permissions to go that far.
This worked on a folder of mine containing over 11,000 files and directories. I verified the setting took effect on a few dozen in various locations and they were all changed accordingly.
Im looking for some help on a batch file for managing NTFS permissions through a batch file.
I have created a folder containing several subfolders. The main folder is shared through NET SHARE command and is working. Now I need to set NTFS permission through command-line commands in batch file.
I need to remove access for any users except admin and a specific user.
i can add the specific user through ICACLS C:\bruger2\jesper /grant:r jesper:f
but the remove part wont work
ICACLS c:\bruger2\jesper /remove Users
Nvm guys, I found the answer.
I needed to include /inheritance:r to remove inherited NTFS permissions
ICACLS C:\bruger\jesper /inheritance:r /grant:r jesper:f Holms:f
How can I grant permissions to a user on a directory (Read, Write, Modify) using the Windows command line?
As of Vista, cacls is deprecated. Here's the first couple of help lines:
C:\>cacls
NOTE: Cacls is now deprecated, please use Icacls.
Displays or modifies access control lists (ACLs) of files
You should use icacls instead. This is how you grant John full control over D:\test folder and all its subfolders:
C:\>icacls "D:\test" /grant John:(OI)(CI)F /T
According do MS documentation:
F = Full Control
CI = Container Inherit - This flag indicates that subordinate containers will inherit this ACE.
OI = Object Inherit - This flag indicates that subordinate files will inherit the ACE.
/T = Apply recursively to existing files and sub-folders. (OI and CI only apply to new files and sub-folders). Credit: comment by #AlexSpence.
For complete documentation, you may run "icacls" with no arguments or see the Microsoft documentation here and here
You can also use ICACLS.
To grant the Users group Full Control to a folder:
>icacls "C:\MyFolder" /grant Users:F
To grant Modify permission to IIS users for C:\MyFolder (if you need your IIS has ability to R/W files into specific folder):
>icacls "C:\MyFolder" /grant IIS_IUSRS:M
If you do ICACLS /? you will be able to see all available options.
Open a Command Prompt, then execute this command:
icacls "c:\somelocation\of\path" /q /c /t /grant Users:F
F gives Full Access.
/q /c /t applies the permissions to subfolders.
Note: Sometimes "Run as Administrator" will help.
Use cacls command. See information here.
CACLS files /e /p {USERNAME}:{PERMISSION}
Where,
/p : Set new permission
/e : Edit permission and kept old permission as it is i.e. edit ACL instead of replacing it.
{USERNAME} : Name of user
{PERMISSION} : Permission can be:
R - Read
W - Write
C - Change (write)
F - Full control
For example grant Rocky Full (F) control with following command (type at Windows command prompt):
C:> CACLS files /e /p rocky:f
Read complete help by typing following command:
C:> cacls /?
I try the below way and it work for me:
1. open cmd.exe
2. takeown /R /F *.*
3. icacls * /T /grant [username]:(D)
4. del *.* /S /Q
So that the files can become my own access and it assign to "Delete" and then I can delete the files and folders.
Corrupt Permissions: Regaining access to a folder and its sub-objects
Although most of the answers posted in reply to the question have some merit, IMHO none of them give a complete solution. The following (might be) a perfect solution for Windows 7 if you are locked-out of a folder by corrupted permission settings:
icacls "c:\folder" /remove:d /grant:r Everyone:(OI)(CI)F /T
For Windows 10 the user/SID must be specified after the /remove:d option:
icacls "c:\folder" /remove:d Everyone /grant:r Everyone:(OI)(CI)F /T
.
Notes:
The command is applied to the specified directory.
Specifying the user "Everyone" sets the widest possible permission, as it includes every possible user.
The option "/remove:d" deletes any explicit DENY settings that may exist, as those override explicit ALLOW settings: a necessary preliminary to creating a new ALLOW setting. This is only a precaution, as there is often no DENY setting present, but better safe than sorry.
The option "/grant" creates a new ALLOW setting, an explicit permission that replaces (":r") any and all explicit ALLOW settings that may exist.
The "F" parameter (i.e. the permission created) makes this a grant of FULL control.
The "/T" parameter adds recursion, applying these changes to all current sub-objects in the specified directory (i.e. files and subfolders), as well as the folder itself.
The "(OI)" and "(CI)" parameters also add recursion, applying these changes to sub-objects created subsequently.

ADDENDUM (2019/02/10) -
The Windows 10 command line above was kindly suggested to me today, so here it is. I haven't got Windows 10 to test it, but please try it out if you have (and then will you please post a comment below).
The change only concerns removing the DENY setting as a first step. There might well not be any DENY setting present, so that option might make no difference. My understanding is, on Windows 7, that you don't need to specify a user after /remove:d but I might be wrong about that!

ADDENDUM (2019/11/21) -
User astark recommends replacing Everyone with the term *S-1-1-0 in order for the command to be language independent. I only have an English install of Windows, so I can't test this proposal, but it seems reasonable.
I struggled with this for a while and only combining the answers in this thread worked for me (on Windows 10):
1. Open cmd or PowerShell and go to the folder with files
2. takeown /R /F .
3. icacls * /T /grant dan:F
Good luck!
With an Excel vba script to provision and create accounts. I was needing to grant full rights permissions to the folder and subfolders that were created by the tool using our administrators 'x' account to our new user.
cacls looked something like this:
cacls \FileServer\Users\Username /e /g Domain\Username:C
I needed to migrate this code to Windows 7 and beyond. My solution turned out to be:
icacls \FileServer\Users\Username /grant:r Domain\Username:(OI)(CI)F /t
/grant:r - Grants specified user access rights. Permissions replace previously granted explicit permissions. Without :r, permissions are added to any previously granted explicit permissions
(OI)(CI) - This folder, subfolders, and files.
F - Full Access
/t - Traverse all subfolders to match files/directories.
What this gave me was a folder on this server that the user could only see that folder and created subfolders, that they could read and write files. As well as create new folders.
Just in case there is anyone else that stumbles on this page, if you want to string various permissions together in the one command, I used this:
icacls "c:\TestFolder" /grant:r Test_User:(OI)(CI)(RC,RD,RX)
Note the csv string for the various permissions.
XCACLS.VBS is a very powerful script that will change/edit ACL info. c:\windows\system32\cscript.exe xcacls.vbs help returns all switches and options.

Bulk folder creation and grant permission works me by using the below powershell script.
Import-Csv "D:\Scripts\foldernames.csv" | foreach-object {
$username = $_.foldername
# foldername is the header of csv file
$domain = “example.com”
$folder= "D:\Users"
$domainusername = $domain+“\”+$username
New-Item $folder\$username –Type Directory
Get-Acl $folder\$username
$acl = Get-Acl $folder\$username
$acl.SetAccessRuleProtection($True, $False)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("SYSTEM","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("$domain\Domain Admins","Read", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule($domainusername,"Modify", "ContainerInherit, ObjectInherit", "None", "Allow")
$acl.AddAccessRule($rule)
Set-Acl $folder\$username $acl
}
Note: You have to create same domain username in csv file otherwise you will get permission issues

excellent point Călin Darie
I had a lot of scripts to use cacls I move them to icacls
how ever I could not find a script to change the root mount volumes example: d:\datafolder. I finally crated the script below, which mounts the volume as a temporary drive then applies sec. then unmounts it. It is the only way I found that you can update the root mount security.
1 gets the folder mount GUID to a temp file then reads the GUID to mount the volume as a temp drive X: applies sec and logs the changes then unmounts the Volume only from the X: drive so the mounted folder is not altered or interrupted other then the applied sec.
here is sample of my script:
**mountvol "d:\%1" /L >tempDrive.temp && FOR /f "tokens=*" %%I IN (tempDrive.temp) DO mountvol X: %%I
D:\tools\security\icacls.exe %~2 /grant domain\group:(OI)(CI)F /T /C >>%~1LUNsec-%TDWEEK%-%TMONTH%-%TDAY%-%TYEAR%-%THOUR%-%TMINUTE%-%TAM%.txt
if exist x:\*.* mountvol X: /d**
I am Administrator and some script placed "Deny" permission on my name on all files and subfolders in a directory. Executing the icacls "D:\test" /grant John:(OI)(CI)F /T command did not work, because it seemed it did not remove the "Deny" right from my name from this list.
The only thing that worked for me is resetting all permissions with the icacls "D:\test" /reset /T command.
navigate to top level directory you want to set permissions to with explorer
type cmd in the address bar of your explorer window
enter icacls . /grant John:(OI)(CI)F /T where John is the username
profit
Just adding this because it seemed supremely easy this way and others may profit - all credit goes to Călin Darie.
When I ran the command:
icacls "c:/path/to/folderA/folderB" /grant:r Everyone:(OI)(CI)F /T
None of the files in folderB were being processed, which was indicated via the output message:
Successfully processed 0 files; Failed processing 0 files
However, once I changed the specified path to the parent directory("c:/path/to/folderA") and re-ran the command all the files in folderB were successfully processed.
Note: If you want any other files/folders in folderA to not be processed, try moving all those files/folders to a different location before running the command above.
Hope this helps anyone running into the same issue.
i was not able to open any file in a drive, this command unlocked all -
icacls i:\* /grant Users:F /t /q /c
in windows 10 working without "c:>" and ">"
For example:
F = Full Control
/e : Edit permission and kept old permission
/p : Set new permission
cacls "file or folder path" /e /p UserName:F
(also this fixes error 2502 and 2503)
cacls "C:\Windows\Temp" /e /p UserName:F
This is what worked for me:
Manually open the folder for which the access is denied.
Select the Executable/application file in that folder.
Right-click on it and go to Properties -> Compatibility
Now see the Privilege Level and check it for Run As Administrator
Click on Change Settings for all users.
The problem is solved now.

During my NSIS setup script for a WinForms app, I use the following CACLS command to give the Users group full rights to a subfolder:
Exec 'CACLS "$INSTDIR\SubFolder" /E /T /C /G "Users":F'
So in effect the CACLS command executed is something like:
CACLS "c:\Program Files\MyApp\SubFolder" /E /T /C /G "Users":F
When I then look at the Folder permissions in Windows Explorer (right click on the folder and choose Properties, go to the Security tab), the correct permissions are there but they are uneditable.
Furthermore, clicking the Advanced button for the 'Advanced Security Settings' shows that SubFolder is inheriting the "Users" group permissions from a 'Parent Object', but what is that Parent Object, because its not the folder above.
Why are the permissions added by CACLS uneditable, and why are they inherited from nonexistent parent object? I thinking I may have set the options on CACLS wrong.
I'm on Windows XP.
I think I figured it out: Changing CACLS to use /P 'replace' rather than /G 'grant' seemed to work better:
CACLS "c:\Program Files\MyApp\SubFolder" /E /T /C /P "Users":F
The options that got created were then editable in the Windows Explorer 'security' tab.
NSIS has a plugin to set permissions, you should probably use that (I can't remember if XP Home even has cacls)
The inherited permission for "Users" has to come from somewhere clearly, either the root of the drive or a parent of your parent folder (The advanced security dialog should have a inherited from column in the list)
Using the command:
iCACLS.exe \\server\serverroot\siteroot /grant:r domain\id:RX /T /C
I can grant access to every file within the site root folder, but the folder itself does not receive the access. The problem being any new file that gets added lacks the read access until the command is run again. What am I not understanding?
The reason the folder itself does not receive the access is because I did not tell iCacls I wanted it to make the access inheritable. The command should be:
iCACLS.exe \\server\serverroot\siteroot /grant:r domain\id:(OI)(CI)(RX) /T /C
Does exactly what I need (and for predictable reasons. I like that.)
