Title sums it up. Recently, a folder appeared in my gallery called "cache". In it are 4 files: 2206smaller-background 435smaller-background-land-wide 2352background 4460background-land-wide The numbers that start the files seem to change every time I delete them and restart the phone - as does the creation time and date. Almost as if the phone is creating these files rather than them being old ghost files i can't delete. I have deleted the gallery cache but that had no effect. The phone shows that the location of the folder is "unknown". I keep deleting the files and the folder and they just keep coming back. I have searched for these files all over the phone and SD card to no avail. They are not in my picasa account nor do I have a clue where they came from.
