So, theres this file that appeared in my sd card called "usbcçh_." for no apparent reason, and now if i try to delete it, or the folder that its in, my computer just says "The filename you've specified is either invalid or too long. Specify a different filename." and when i try to open it my computer says "The specified path does not exist. Check the path, then try again." I really have no idea what to do, so if anyone has any suggestions, or knows about anything about this, any help would be appreciated.
