I am glad Williebee was able to help you, Kevin. I, too, save multiple copies of everything. My original MS never gets touched once I write it. It's not even in proper MS format. The file name is always called First Draft and I make a copy as soon as I'm done called Second Draft and so on and so forth.
We also have a program called iBackup that runs all the time. It backs up my files any time a change is made. I've not needed to restore anything yet, but those copies are there if I need them.
And Williebee, if you are reading this, thank you for being an awesome help to another AWer!
