What save slots are autosaves?
 

I have about 800 mb of saves due to quick saving often and now after finishing the game I'd like to remove the useless saves. Do autosaves have certain numbers in the SaveGames folder or are they there randomly? For example save number 000 is the final autosave after finishing the game.

In NecroVisioN, autosaves don’t have special numbers or labels—they’re mixed in with manual saves and numbered sequentially. So no, save000 isn’t always an autosave—it’s just part of the order.

Best way to clean up: sort by date modified and delete the older ones.
