If you've been using Word, you can find the location of the 'autorecover' files very easily.
Go to 'Tools', 'Options' and click on the 'File Locations' tab. Under 'File Types' you should see 'Autorecover Files'. Alongside that, under 'Location', you will find the exact location of those files. You can then open the file and 'Save As' to wherever you want.
Mind you, that depends on the autosave settings, found under the 'Save' tab in Options. [My autosave interval is set to 5 mins - you don't see it happening!]
Best of luck!
