Ever have that annoying problem where when you detach a database or stop sql and then go to copy / move the files and find you don't have permissions to the files ?  ACL (access control list) and NTFS permissions can be very annoying but they are manageable.

I found a nice script for "take ownership", right click menu and it worked nicely, allowed me to take ownership and then add the sql service account back to the ACL for the file(s) and all was good.
