My friend rescently downloaded a video on limewire that said it was 4MB big. When he ran the video it lasted barely 2 seconds and afterwards the file became undeletable. when i right clicked the file the option to delete or look at file properties was not available. When trying to delete the file using other methods there was no response. I cannot move or even rename the file, and when i looked at the file properties using the menu option the file size was zero and there was no file extention. The video ran only once and does not play now. My question is : How do i delete a file that's not even there? even thoguh i can see it in the folder?
