PokerTracker4 will auto/manual import a .dat file no matter where the file is, we get them from customers from time to time to investigate a particular problem and to be honest I'm not sure I've ever run into one that PokerTracker4 wouldn't at least try to import from - might your trouble be the backup(s) had no hands in it, or possibly the file was corrupt, etc.? Was this an actual import error? Or PokerTracker4 just didn't see the file so you couldn't even try the import?
We'd be happy to look into the matter if you want to compress one you're having trouble with and send it in a ticket here: https://support.pokertracker.com/support/ticket/6
If the compressed copy ends up being larger than 5M so unable to be attached to your ticket you can open the ticket anyway to tell us the situation and we'll provide an upload link you can send it to.
