OK, I have one of the 0 directories on my sdcard. My question is, which directory is my Nexus using for it's information? I've got to delete some stuff off there, because my storage space is about filled up and I don't need two copies of all the info from my sdcard on there. I am currently running XenonHD 10-23-12, 4.1.2 and wanting to move up to JB Sourcery 4.3, but limited on space right now for backups and the like. Note: Yes, I have read through "The Chief's Quick Guide to Flashing a ROM" but still don't know which to keep.
