When you have to change ACL on huge amount of files (eg. give yourself rights to delete Vista files form a secondary partition 😉 ), you have to way’s to do that:
- sit all day changing ACL to small groups of files repeatedly, cause trying to call „Properties” on a huge amount of files will take forever
- use a command line tool which will set ACL for each file based on wild cards.
I prefer the second solution. Windows has a neat command line tool that does just the thing, cacls, eg:
cacls * /T /G MyUser:F
Of course you have to have rights to change file rights in the first place 😉
