Hi, today I discovered that C was almost 67% full. Ran Ccleaner and Defrag and found an mp4 strange file on C's recycle bin. It's almost 4 GB. Recovered it to watch what it's about (cause I don't use that format at all) and sure the file was corrupt. It's saved on D partition but still apears as a not deleted file on C. What can I do to get rid of it. How did it get there to start with?. Haven't downloaded a video in months (only mkv) and they are on an external hard disk. Says it was created monday april 30th ... I wasn't even home but like 200 kms away from my PC. Kinda weird.
