How things are:
This is how my Games folder looks at the moment:
Hey, look there's a Baldur's Gate 2 catalog in there. Let's see what's inside!
Not so cool, unfortunately.
My file recovery program sees the lost content of the games folder:
After recovering BG2 save folder (and copying it to my other PC with BG2 installed), the load game menu in-game looks like this:
Yeah, it didn't work, and after trying to find single valid files for two hours I am ready to give up.
I don't know if Steam was the cause because I've also recently installed SWAT2 from and old CD on this PC, and uninstalled it after half an hour. Maybe this is at fault here. No idea.
I'm not sure what to do right now. I have some old save files copied, but they are three months old (newest save available is the first part of de'Arnise keep quest). That's a lot of progress lost, including Unseeing Eye quest, and a lot of lich fights, which I really would not like to play through again. I see three possibilities.
1. Play through the quests and resume the LP when I reach the most recent state. This will cause a hiatus, of course.
2. Edit the savegame to reflect current situation (more or less) and continue from there, ignoring the finished quests and assuming them finished. This will cause inaccuracies.
3. Fuck this LP and start some other one. This will cause butthurt.
All these options suck in one way or another and I need to clear my head a bit before choosing one.
