Thanks for the advice, this does work to some extent although some files remain recoverable. I have a couple of programmes that will do this including Microsoft File Shredder. What I find frustrating is the experiance described above where after following the search you highlight or check the files for overwrite and then run overwrite only to get a message that says 0 files deleted in xxx seconds. If you follow this with recovering the files, many of them are fine. Cheers Graham J.
