CACLS/XCACLS CMD - Permissons

Hey, new to the forums, sorry if this is something people have posted many times before, but here goes.

The usual school story, we don't want people accessing our programs etc we use eg. UT2004. We found a batch file in the C:\ which used XCACLS to modify permissions somehow, I can't remember whether it was to restrict or allow.

Anyway, can this be used to allow access to certain things? And, can I use it to stop others from opening my files? Again, sorry if this is a N00Bish post. I've looked on google, I have a vague idea on how to use it…

Thanks,

You can use Xcacls.exe to set all file-system security options that are accessible in Windows Explorer from the command line. Xcacls.exe does this by displaying and modifying the access control lists (ACLs) of files.

Check out microsofts websites if you have cmd problems first. I did it for you this time. Hope this helps you.

Thanks, I'd already checked their website. I was just wondering if anyone knew just how far I could take it… Do you need Full Control permissions to change permissions using it? Thanks, and sorry if I'm just wasting your time.
