I just rooted for the first time, installed xtrsense. Then I realized all my old junk is still stuck on my SD card (mainly game save files and youtube downloads). Since deleting every non-important folder would take too long, is it safe to simply Settings>SD Card>Format? I can't stand clutter, and I'd like to treat my freshly rooted phone as.. well.. fresh. I assumed that the "Wipe Data/Factory Reset" step would remove everything, but I guess that doesn't affect the sd card. Please save me from a boatload of manual cleaning On a related note, I'm planning to buy a bigger/faster card. Can I safely switch it out without screwing with anything?
