Okay, basically, I have a ton of roms on my SD card (more than 2 gigs) for an M3 (not the lite, but whatever people are calling the side loading one that is slightly smaller). None of these have been trimmed, because I wanted to maximize compatibility, and I have a 4 gig SD card anyway. However, I just got a new PDA that supports 4 gig SD cards, so I was hoping to switch the 2 gig memory card from my PDA into the M3, and put the 4gig memory card into my PDA. However, since I have over 2 gigs worth, I need to start trimming the roms The problem I'm having is that I don't remember any of the settings that worked well on the roms on my SD card, and don't wan to go through trial and error again on that many roms. I was wondering if there was any standalone program that can just trim out the empty space in the rom but also let it still work with the M3. This is probably too much to ask, but I was hoping I'd be able to save the trouble. Any ideas?
