I have tens of gigs of Renpy games that I just can't delete outright, why? Save games are always saved inside the folder which makes deleting games by the dozen impossible or suicidal. You have to go inside every individual game and delete all but the save folder, doing this every time for every single game when it gets updated is such a pain. Anyone has a better way?
Ren'py, at least with a Windows based system, places save files in a (typically) hidden folder (%appdata%) under the Users folder for your particular Windows login... So you can delete a Ren'py games main folder with all the game files and so on, but the save files will still be available for the next time you install the game again, or install a new version...
Will those save files be compatible with a new version? That is entirely up to what changes were made... In many cases, especially with earlier versions of a Ren'py game, I've seen some or all of the save files just cause errors with some updates... Again, it depends on the alterations made to the coding in the updated game, if older save files will work or cause the game to break down...
If you don't want to keep old save files, you'll need to go into that Appdata folder, under Roaming you'll find Ren'py, and in there will be folders for every Ren'py game you've ever made a save file for... Remove that particular game folder to get arid of the older save files...
