How to replace a user "aaa" in all ACLs of a dir tree with user "bbb" ?
Assume I have a (big) directory tree with top node D:\data\log\
Some but not all of the containing folders and files have ACL access permissions for an (outdated) user "aaa".
How can I replace in all the ACLs where this user appears the user by another user "bbb"?
I am a third user "ccc" which is member of the "Administrators" group.
