I just rooted my phone last night using revolutionary and while creating a backup it said my sd card was full and couldn't complete. I deleted and cleared data on spotify and deleted all my music which free'd up about 3 gb. I have no videos and about 20 pictures on phone, but my sd memory card only shows I have 2.74 gb available. after completing a complete back up which took up 1.4gb i now have 2.74gb available. My question is where in the heck is the other 5.26 gb of free space??? I only have about 20 apps downloaded some to sd card some not. What is taking up all this space on my sd card??
