syntax
      XCACLS filename [options]

XCACLS filename
key
If no options are specified XCACLS will display the ACLs for the file(s) options can be any combination of:

/T Traverse all subfolders and change all matching files found.
/E Edit ACL instead of replacing it.
/R user Revoke specified user's access rights. /D user Deny specified user access, this will over-ride
all other permissions the user has.

/C Continue on access denied errors. /Y Replace user's rights without verify

/P user:permision;FolderSpec
Replace user's rights. see /G option below

/G user:permision;FolderSpec
Grant specified user access rights, permision can be:
:r Read :c Change (write) :f Full control
:p Change Permissions (Special access) :o Take Ownership (Special access) :x EXecute (Special access) :e REad (Special access) :w Write (Special access) :d Delete (Special access)

FolderSpec is a permission applied to a folder.
Folder permissions are inherited by new files added to the folder.
If FolderSpec is not specified then permission will apply to
both files and folders.

FolderSpec: T@ where @ is one of the rights above, when this is specified new files will not inherit folder permissions. At least one folder access right must follow T Entries between ';' and T will be ignored.

Wildcards can be used to specify more that one file in a command. You can specify more than one user in a command. You can combine access rights.

For example:

Allow guests the right to read and execute in myFolder
XCACLS myFolder /E /G guests:rx

Allow guests the Full Control permission in myFolder and all subfolders
XCACLS myFolder /T /E /G guests:f

This will grant guests only read access to all files in and below myFolder,
new folders created will be Read Access only, new files will not inherit any rights.
XCACLS myFolder /T /P guests:R;Tr

This will grant guests only execute access to all files in and below myFolder
XCACLS myFolder /T /P guests:x
