is there a way for locking completely an edited file in perforce? I know that if user A edit a file he could lock it, but this lock does not deny a different user B to edit the same file as the lock is used just to deny the submit of the file from user B before A has unlocked it. How can i deny the user B to open the file for edit if the file he wants to open is already opened by a different user? thanks in advance. Filippo Ignozza Filippo Digital Video S.r.l.
