Has anyone else had this problem? I did a system recovery recently on my Windows XP system, and a folder called "My Old Disk Stucture" was created in the root drive (all my old files). I have tried everything and cannot delete this folder. What's REALLY strange is that I was able to delete the contents so now the folder appears to be empty, but the computer thinks it's a 3 GB folder. Any attempt to delete eventually is interrupted with the error message: Error deleting File or Folder. Cannote delete Dc4. Access is denied. Make sure the disk is full or write protected and that the file is not currently in use."Have you tried deleting it in DOS?

Someone else also suggested that to me this morning. But they also warned that there may be something important in that folder that potentially could screw things up if deleted, so I'd better back up any important documents. I'm THINKING that if it's my old disk structure, then it shouldn't affect anything at all. Would you agree with that?It depends on what is in your old disk structure folder ...was this an upgrade if so it may contain files needed for your upgrade...as is  a microsoft its conning the user to believe that they have a brand new o/s...as files are used from the old system...and also if the user get fed-up with windows xp they can uninstall it if they wish?always pays to check any folder deletion anyways...>PLAY safe it pays..
