I've gotten this to work on my computer, but I'm not 100% sure if it is what you want:
Echo Y| cacls %1 /t /e /c /g %2:F
place in a batch file, and call that batch file like so:
batch <folder> <username>
in your case <username> would be "everyone".
two reasons I think it doesn't meet your requirements:
- it processes files, not the entire drive
-it also seems to only work with the files in the root dir (when given a root dir)
I'll use my physic powers: T:[$TEACHERS$], J:[CLASSES], W:[WINOLDAP] and more
was I right? do I win a cookie?
