Cacls comes with Windows NT4.0/2000/XP. It is used to add or remove security permissions to files and folders. It is very handy, for example, if you wanted to add the administrator group to a bunch of files without changing the other security settings.

cacls /T /E /G administrator:F d:\users\*.*
Cacls will add Full Control for the administrator account to all files and subfolders in the Users folder of the D:\ drive.

cacls /T /E /R Everyone d:\users
Cacls will remove all permissions for the 'Everyone' group in all files and subfolders in the Users folder of the D:\ drive.

WARNING! Be sure to use the /E switch when you are just making modifications to the ACLs of a file. Without the /E switch, your settings will replace the current security with only what is specified.
