Apologies if this has been asked before, but I'm in a bit of a pickle.

I was working on a word document and deleted a lot of the content. I
then accidentally saved the file. Is there any way I can recover the
previous saved version??

I know, pretty stupid thing to do, but I really need to get the
previous version back.
Is there a tool out there to do it, or am I 100% guaranteed that the
previous version will have been overwritten?


TIA
