Rufus' Solution Works, but on windows 7, I could only navigate to the folder in CMD by typing cd [space] then the path: "cd C:..." rather than cd//C:..." Maybe that's what you meant rufus, but I didn't realize that, thought this might help others.
Solution:
- Open command prompt
- Go to the folder where the file is located (use command cd foldername to enter in to a folder and cd// to come out of a folder) and type del filename.mkv don’t press ENTER.
- Open windows task manager (Ctrl+Alt+Delete) and go to processes tab and locate explorer.exe , right click on it od select end process (not end process tree). don’t close the task manager .
- Go back to command prompt and press enter. Now the file is deleted.
- Go to task manager again and select file>New Task and type explorer.exe and press ok .
