It would be nice if he could give specific error messages, e.g.
"Can't write %s because it is locked by %s."
vs.
"Can't write %s because you don't have write access."
I can't speak for Ali, but I'm always annoyed by error messages
listing several possible cuases, such as "Can't delete file,
because the source or destination is in use".
