That folder now has only the un-labeled newly restored from seed wallets, as it goes to a folder that is a work folder I never set, but made backups to.

Just to add to the confusion, is it possible that a few failed seed-recovery attempts (while looking for the right hot wallet seed that I'd saved) might have caused the over-writes of the wallets?  

In other words, when I couldn't find the 'new' hot wallets I made a few attempts to restore from seed.  At no point, though was I given a 'file exists' warning.  

In the Windows Roaming directory with the wallets I've found I found a 'default_wallet.deterministic' and a 'default_wallet.imported.'  

That was probably that split wallet before one of my seed attempts over-wrote them?
