Recovering an overwritten document

[kitman]

Hello,



I hope you can help. I have two copies of a long word document I have been working on. I decided to copy the document in to my external hard drive from my C drive document folder.
So I did this but then realised I had been using the external drive copy so now it was overwritten. I clicked on undo (i think it was undo and not redo) but the document disappeared from the external hard drive. I then clicked on undo/redo and it reappeared but was still the older copy.
I cannot find a way of finding the most recent version of the document.
I did try right clicking on the document and restore previous versions but it's empty.
I hate to think that five days work has gone. Please tell me it hasn't

Regards

Kit
