Well,

The first thing to do is to get her to go into Word and change the options so that it automatically saves and that it automatically makes a backup. When you close your document it will create a copy as a .bak file. The auto save will do a save every "x" minutes that you specify, I would recommend 10 but if I have done something complex I do a manual one in between by clicking the green floppy disc icon on the toolbar.



PS might be worth checking to see if the backup option was turned on.............it should be a .bak extension file with the same name as the .doc one
