OK, Sorry I didn't specify things, in a bit of a panic.
Hazelnut,
Running Windows XP
Only one account, one user.
Ran the regular cleaner, then registry cleaner and then Wipe Free Space.
Did back up before (Unable to locate back up file.)
All corrupted files where on D drive. Operating files are on C drive seem to be untouched.
Word Doc's, picture files, video files, and I Tunes music collection all same results.
Properties of D drive says it is still 95% full, as it was before 'CCleaning' so feel (dreaming) they may still be there, just completely jumbled up.
Augeas,
Have had CCleaner for a good while, no problems before. Upgraded and ran it once, regular clean, no problems. Ran again and used Wipe Free Space and this is when things went belly up.
Downloaded from Piriform website, filehippo link.
Everything is/was on D drive, regular 'documents' file, 'pictures', 'video's and 'I tunes Library' etc.
Not sure what else I can add.
Think I am 'Wiped' Royally! Six plus years of pic's, video's, docs etc gone!
