I take it you're on stock ROM? I used it for all of an hour before I went into flashaholic mode, so I'm not too sure.
I do know the stock ROM has a built in file manager though. Could you try moving your downloaded files into different folders? I know it's not really a fix, but it might be a convenient work around... And it'll promote keeping a clean file system for various types of files you download.
