Originally posted by Mouse: Even if you have deleted them and cleared the recycle bin, it might be posssible to recover some of them via a third party "undelete" type programme. Norton Utilities has one IIRC. Best of luck.

You don`t need a thirdparty program, you can do it through MS DOS... *if* nothing else has been saved to that drive yet, you can probably get it all back.
Start -> Run -> Command
Type:
UNDELETE C:/ALL

If i`ve got the right syntax, and it still works, then you should be able to get atleast some of it back... but, this isn`t something to rely on. In future, make *SURE* your work is backed up, say, once a week. That way, you have another copy and you`re no more than a week behind.
