What does Code:
say from the Terminal
I tried this listing but one needs 'O' option to see all the nice (depends, it took many hours to find out the cause) things in Mac OS X or BSD derivates..
did the trick!
sudo chflags -R nouchg /path/to/files
Somehow I was faced with "User immutable flag" whatever in earth it is.. never heard and it wasn't me (can't be ;) to enable those flag here and there but not everywhere thou.
