I finally installed an updated Electrum after using 2.5.4 for the past year or so and my hot wallet, with all of my labels to transactions has been lost.  I restored it fine - but the process for losing it was truly scary and a mess.

When I attempted to load my old hot wallet I got a message saying something about unsupported multiple identity wallets? (which I had no idea my hot wallet was) and that it would now 'Save' it to a couple of wallets with the locations of the new files.  I said OK, assuming idiotically that I'd be able to find them in the default wallet location folder. 

I have no idea what happened.  I've looked for them in the AppData/Roaming/Electrum/wallets folder.  I run searches on today's modified *.dat files and now I'm just at a loss.  Where are they? 

I recovered the wallet through the seed, but I really need my labels for my taxes.

I'm an old progger.  And I feel that this was a mess.  I don't care what your program is supposed to do, but user data is sacrosanct.  It seems that 'default_wallet' gets over-written under certain circumstances? 

Sorry to rant, but I'd appreciate any help in finding my old wallets and where 2.7.18 put them.
