xcacls is little known, i guess that's a disadvantage. it's freeware, so it's not supported by microsoft like cacls is. in some companies, you may have policies in place that forbid running software like this. it's part of the resource kit, but is freely downloadable from Microsoft. here is a brief syntax comparison between cacls and xcacls.

for this simple application, cacls is a good choice. for more powerful uses, specifically when combining access rights, xcacls adds value.
