Okay, thanks for the quick replies. Apologies for not explaining clearly:
User was working on VW file
VW crashed
User lost changes made to VW file since last save (changes significant enough to worry him)
What I wondered was, does VW generate a 'temporary' copy of the file when it's open like MS word does? The file is removed when the file is saved, so if VW crashed and couldn't give the order for the file to be removed could it still be got at?
I know the user should be saving his files regularly and yes he's ultimately to blame. But of course I need to made all reasonable efforts to help him out.
Many thanks.
