Intuit doesn't keep copies of any client files, sorry.   

If you didn't save a backup copy and they've all been deleted from your hard drive, you'll have to recreate them from your paper copies you kept....assuming you DID keep a hard copy somewhere.

You may want to invest in an automatic cloud backup program like Carbonite, it backs up the folders of your choice continuously so if you ever crash, you'll have a backup of the files.
