Realplayer Downloaded File

hi everyone, I’m having a huge problem with some videos I download from Youtube with Realplayer. I would download the .flv files and convert them to put on my Sansa Fuze. But, the original .flv files can’t be deleted now for some reason. I don’t think the computer recognizes them because I can’t change the name or look at properties, but I could make another copy of 1 on the desktop =_=…

Does anyone have a good solution for me?

Try running ChkDsk on them. See this post for the command line syntax.
