Is it okay to rename P2 cards? I'm trying to create a simple Automator workflow. The problem I'm having is that the mounting of the 2 P2 cards in the camera is random, so there's no way for me to know which one is Card 1 and which is Card 2 unless I manually check the date on the LASTCLIP.TXT file. On my Mac they are both name "NO NAME" without a "NO NAME 1". Can I just name them Card1 and Card2 if I'm not going to format in the camera?
