So, Ive got a file on my external hard drive that I have no idea how it got there. Its full of other files and random shit. I try to delete it and originally I got the message sayin I need permission from SYSTEM. I changed all the user permissions to allow full control, and nothing changed. I changed the owner of the folder to my own account, instead of SYSTEM, and still nothin. I booted in safe mode and tried to delete, still nothin. What else can I do?
