I'm trying to clean up my LG Vu of "other files" and I have one that is 4Mb in size, stored in the "other files" location, and it cannot be deleted.

Anyone have any idea what this "USBSe." file could be, and what it could be using. It doesn't say it's in use by another program...it says it's using another program. It has no file extension, or any other information, with the exception of its size.


I'm trying to clean up that folder b/c I believe it's causing the phone to run slower when accessing music & picture files, and with it being 4Mb in size, I think it could be the culprit. Others have cleaned out their folder and their phones have gotten faster.
