I found this Python script a few years ago, it is simple enough that a non-programmer could understand 90% of it. I just remembered it had been running as a scheduled task all this time when I thought I had lost some saves.

Thought I’d post it here in case anyone can use it. Minor things are hard coded but they are few and easy to edit.

      Same. Dozens, maybe hundreds of files most of them 250-300MiB.

      The nice thing about automation is I have no idea, it just works!*

      • (As long as your save files are in one parent directory… and not in a place with other “zip” files)
