I was browsing through Root Explorer, cleaning out some files, etc. and I noticed a file in the main "sdcard" path titled "music2_hprof_data". I'm not entirely sure what it is but it's averaging around 50MB. I've tried doing some research but I literally have come up with no results. Can anyone give me any insight on what this file is? The only thing I can really think of is that it might have something to do with caching my Play Music - although usually the music cache is in the Android/data path.
