Perms.exe: File Access Permissions per User

Perms displays a user's access permissions for a specified file or set of files.

To use Perms, you need "Backup files and folders" privileges on the computer where the files are stored, and you must be logged on as a member of the Administrators group for the domain or computer where the user account is defined. Otherwise, "Access denied" errors might occur.

Perms queries the permissions associated with a specific ACE, displaying only those permissions granted by that particular ACE.

Note that if a user is a member of local or global groups with varying sets of permissions, PERMS output does not reflect cases in which this user has been given or denied rights through the ACEs for these local or global groups. The following scenarios illustrate this point:

• In this case, Perms would show that username has FULL ACCESS, while in fact he or she has NO ACCESS.
• In this case, Perms would show that username has READ ONLY permission, even though he or she actually has FULL ACCESS.
