My phone just warned me about not having enough space. I store all my media on an external card so I was confused. I mounted the phone and began to go over each directory. I found the attached one which I have no idea what it is. It is using 6 gb of space.

It is in /sdcard/470808579740795203/. The two large files are in separate sub directories and are called "cpbdf". Thats it.

Anyone have any idea what this is?
