Here is a simple guide on how to find the saved games folder locations.
Note: Ultimate ADOM is now fully released on Steam along with Massive Content Update on Aug 25!
Where is the saved games folder located?
E:\Documents\Team ADOM\Ultimate ADOM\CavernsOfChaos\Steam\SavedGames
For you, replace “E:\Documents” with your “My Documents” folder location.
You will find .uas and .bak files inside there.
(.uas probably stands for Ultimate Adom Save)
For example,
6146b14b-014b-4461-a0fc-76a1a4e9fabc.bak
6146b14b-014b-4461-a0fc-76a1a4e9fabc.uas
If you want to “save scum” then just copy these files and paste them in a new folder in order to backup them.
