So I decided to go through the HTC clean-up app to get rid of some used data. I was really surprised when when I 14GB+ in temp files. So I decided to delete them. Well I guess that included all my music, and temp files. When I go in to WinAmp, HTC music, or Play Music, all of my songs are still listed. ES File explorer shows the data is gone. I have a back- up of all of this in Play Music and two different laptops so not a big deal. I guess I should have done the math And added up the temp files + music files and the gallery and realized the total used storage was more than what I was actually using. So, no big deal, but I don't advise anyone to use this function.
