NO! ABSOLUTELY NOT TRUE IN ANY WAY, SHAPE, OR FORM. IT IS IMPOSSIBLE TO PROTECT A FILE BY LOCKING IT. PERIOD. ABSOLUTELY NOT. IT DOESN'T HAPPEN. The only way to protect a file is to have it on a locked volume. Now I don't know if SAM is beyond this, because I haven't tried it...yet (hey, c'mon, I read newsgroups on Internet in what little free time I have between my job at xxx and handling the lab here. However, I have an "utility" which will overwrite any resource in any file, and that's all the more specific I am going to get about it because I don't want some amateur hack reading this to get any ideas. Saying that it can be done is bad enough - it encourages the ones that don't know ... yet. At any rate, file locking AND PROTECTING (via some sector editor) do not stop this "utility" from working - no, it's not ResEdit, but I haven't tried ResEdit, although I would assume that it won't work. So, there is NO WAY to stop a file on an unlocked volume from being written to, changed, etc. Sorry. Mike. Mac Admin WSOM CSG CWRU mike@pyrite.som.cwru.edu
