JSI Tip 8225. The Extended Change Access Control List tool (Xcacls.vbs) has been enhanced and replaces Xcacls.exe.


The Xcacls.vbs tool modifies and displays NTFS file system permissions on folders and files.

Xcacls.vbs can now set all the file system security options that are available in Windows Explorer.

NOTE: Xcacls.vbs works with Windows 2000, Windows XP, and Windows Server 2003.

Download XcaclsInstaller.exe file.

Double-click the XcaclsInstaller.exe and extract Xcacls.vbs to a folder in your path.

The Xcacls.vbs script should be run with Cscript.exe. To change the default script engine, type cscript.exe /h:cscript at a CMD.EXE prompt and press Enter.

When I typed xcacls.vbs /?, I received:

Arguments Used:
        Filename is required and was not passed as an argument.


------------------------------------------------------------------
---------------------------- Usage -------------------------------
------------------------------------------------------------------
Displays or modifies access control lists (ACLs) of files & directories

XCACLS filename \[/E\] \[/G user:perm;spec\] \[...\] \[/R user \[...\]\]
                \[/F\] \[/S\] \[/T\]
                \[/P user:perm;spec \[...\]\] \[/D user:perm;spec\] \[...\]
                \[/O user\] \[/I ENABLE/COPY/REMOVE\] \[/N
                \[/L filename\] \[/Q\] \[/DEBUG\]

   filename            \[Required\] If used alone, it Displays ACLs.
                       (Filename can be a filename, directory name or
                       wildcard characters and can include the entire
                       path. If path is missing, its assumed to be
                       under the current directory.
                       Notes:
                       - Put filename in quotes if it has spaces or
                       special characters such as &, $, #, etc.
                       - If Filename is a directory, all files and
                       sub directories under it will NOT be changed
                       unless the /F or /S is present.

   /F                  \[Used with Directory or Wildcard\] This will change all
                       files under the inputed directory but will NOT
                       traverse sub directories unless /T is also present.
                       If filename is a directory, and /F is not used, no
                       files will be touched.

   /S                  \[Used with Directory or Wildcard\] This will change all
                       sub folders under the inputed directory but will NOT
                       traverse sub directories unless /T is also present.
                       If filename is a directory, and /S is not used, no
                       sub directories will be touched.

   /T                  \[Used only with a Directory\] Traverses each
                       subdirectory and makes the same changes.
                       This switch will traverse directories only if the
                       filename is a directory or is using wildcards.
   /E                  Edit ACL instead of replacing it.

   /G user:GUI         Grant security permissions similar to Windows GUI
                       standard (non-advanced) choices.
   /G user:Perm;Spec   Grant specified user access rights.
                       (/G adds to existing rights for user)

                       User: If User has spaces in it, surround it in Quotes
                             If User contains #machine#, it will replace
                             #machine# with the actual machine name if its a
                             non-domain controller, and replace it with the
                             actual domain name if it is a domain controller.

                             New to 3.0: User can be a string representing
                             the actual SID, but MUST be lead by SID#
                             Example: SID#S-1-5-21-2127521184-160...
                                      (SID string shown has been shortened)
                                      (If any user has SID# then globaly all
                                       matches must match the SID (not name)
                                       so if your intention is to apply changes
                                       to all accounts that match Domain\User
                                       then do not specify SID# as one of the
                                       users)

                       GUI: Is for standard rights and can be:
                             Permissions...
                                    F  Full control

                             Note: If a ; is present, this will be considered
                             a Perm;Spec parameter pair

                       Perm: Is for "Files Only" and can be:
                             Permissions...
                                    F  Full control

                                    R  Read

                                    1 List Folder / Read Data
                       Spec is for "Folder and Subfolders only" and has the
                       same choices as Perm.

   /R user             Revoke specified user's access rights.
                       (Will remove any Allowed or Denied ACL's for user)

   /P user:GUI         Replace security permissions similiar to standard choices
   /P user:perm;spec   Replace specified user's access rights.
                       For access right specification see /G option
                       (/P acts like /G if there are no rights set for user)

   /D user:GUI         Deny security permissions similiar to standard choices.
   /D user:perm;spec   Deny specified user access rights.
                       For access right specification see /G option
                       (/D adds to existing rights for user)

   /O user             Change the Ownership to this user or group.

   /I switch           Inheritance flag, if omitted default is to not touch
                       Inherited ACL's. Switch can be:
                          ENABLE - This will turn on the Inheritance Flag if
                                   its not on already.
                          COPY   - This will turn off the Inheritance flag and
                                   copy the Inherited ACL's
                                   into Effecive ACL's
                          REMOVE - This will turn off the Inheritance flag and
                                   will not copy the Inherited
                                   ACL's, this is the opposite of ENABLE
                          If switch is not present, /I will be ignored and
                          Inherited ACL's will remain untouched.

   /SPEC switch        Special Permission for Folder and Subfolders only
                       If this switch is used, and the object is a folder, then
                       one of the switches below would be used instead of the
                       default.
                          A - This Folder Only
                          B - This Folder, Subfolders and Files (Default)
                          C - This Folder and Subfolders

                          F - Subfolders Only
                          G - Files Only

   /L filename         Filename for Logging. This can include a path name
                       if the file isn't under the current directory.
                       File will be appended to, or created if it doesn't
                       exit. Must be Text file if it exists or error will occur.
                       If filename is obmitted the default name of XCACLS will
                       be used.

   /Q                  Turn on Quiet mode, its off by default.
                       If its turned on, there will be no display to the screen.

   /DEBUG              Turn on Debug mode, its off by default.
                       If its turned on, there will be more information
                       displayed and/or logged. Information will show
                       Sub/Function Enterand Exit as well as other important
                       information.

   /TIMEWMI            Turn on to Time WMI use, only shows up in Debug Mode.

   /SERVER servername  Enter a remote server to run script against.

   /USER username      Enter Username to impersonate for Remote Connections
                            (Requires PASS switch)

   /PASS password      Enter Password to go with USER switch
                            (Requires USER switch)


Wildcards can be used to specify more than one file in a command.
Such as:
                                *       Any string of zero or more characters
                                ?       Any single character

You can specify more than one user in a command.
You can combine access rights.

NOTE: When I view the same permissions in Windows Explorer, the output is the same, including the incomplete words.

NOTE: Xcacls.vbs supports wildcards.

Sample Usage:

xcacls.vbs c:\test\ /g domain\testuser1:f /f /t /e
Edits existing permissions, granting Domain\TestUser1 full control on all files in C:\test and it's sub-folders. It doesn't alter sub-folder permissions.

xcacls.vbs c:\test\ /g domain\testuser1:f /s /l "c:\xcacls.log"
Replace permissions, granting Domain\TestUser1 full control on all subfolders in C:\Test. The command logs to C:\Xcacls.log. It doesn't traverse sub-folders, and doesn't alter file permissions.

xcacls.vbs c:\test\readme.txt /o "machinea\group1"
Changes ownership of c:\test\readme.txt to "machinea\group1.

xcacls.vbs c:\test\badcode.exe /r "machinea\group1" /r "domain\testuser1"
Revokes "machinea\group1" and "domain\testuser1" permissions to c:\test\badcode.exe.

xcacls.vbs c:\test\subdir1 /i enable /q
Turns on inheritance on C:\Test\Subdir1, and produces no output.

xcacls.vbs \\servera\sharez\testpage.htm /p "domain\group2":14
Uses WMI to add 1 (Read Data) and 4 (Read Extended Attributes) permissions for Domain\Group2 to the existing set of Domain\Group2 permissions to testpage.htm on remote computer servera, dropping other user and group permissions (no /e).
