re-import .1pux file

Baz depends on what you mean by "usable".

When I thought about coming back to 1Passsword (before 8 was announced), I noticed that with a 1Password membership, you could still use 1Password while offline and even save new items (something Bitwarden can't do).

I took a look at c:/users/mywindowsusername/appdata/local/1Password folder and sure enough, I found a .SQLite file which is the local copy or our vaults.

You should be able to backup the 1Password folder in appdata/local and use it in case you really mess up your online vault even though it is less likely to happen as deleted items are kept for 30 days.

At the very least if someone deletes your account (1Password families comes to mind) that backup could be very useful. There's a subfolder that can be omitted named "app". That's the folder where the program resides.
