lol, looks like a virus or some hidden files to me.
Did your recovering CD formatted your hard-drive also or did it only overwrite everything?
Maybe the recovering CD has put all your ancient stuff in one large file.
Try displaying hiden files and serach for a large file in start->search->search by size or look for a hidden folder in your hard drive root.
If you just used the recovery CD, it is likely that you don't have anything important, so I would recommand you formatting manually your hard drive by reinstalling Windows XP yourself if your comfortable with this kind of operation. If not, believe me, installing Windows XP is REALLY easy, everuthing is done almost automatically and the installation software has a formatting tool and it will ask you if you want to do that, just say yes and reformat in FAT32 file format, not in NTFS.
