one which wasnt saved! Is it possible, will it autosave somewhere, or is it gone?
Don't know about Works, but Word/Office auto-saves a temp file... either a hidden file $~ilename.tmp in the active directory if its an existing file, or something similar inside the windows temp folder (Start -> Run -> %temp% if you don't know the exact location)
But it also depends on *how* it "wasn't saved". If it crashed or you rebooted your computer without saving, then the temp file will likely be there. However, if it asked whether you wanted to save it and you said "no", then most programs tend to delete the temp file in question as well, and it's truly gone.
(After all, it's pretty bad design to keep a file where the creator explicitely said they didn't want it anymore)
