Wow... its been a while since I've posted. Moved from Cincinnati to Fort Wayne, and had to settle with verizon broadband (5 gb month) and now I have to monitor my internet usage... haven't been on in a while. Anyways, My question is on my SD card I have files that are titled DiskCacheIndex##### (the # being an actual number, in a set of five). Anyone know what that is? And do it need them?
