I know this doesn't help this situtation, but I've done so many dumb things on my computer I finally decided that those people that say "back-up, back-up...." may have a point.  But you also have to have some plan during your work -- not just a backup at the end of the day.

I'm working on a covered bridge model in Lightwave.  I just did my 107th. incremental save.  It's so easy in Lightwave (Shift-s) that it's second nature now.  At the end of the day I zip up the versions and copy the zip to a different drive.

I guess a good question here is, is there an easy way to do incremental saves with Lightwave? Maybe an action or script?

Maybe someone here can offer up a good incremental file save solution that's easy to use.
