Delete Empty Folders On Game Close

When the game closes, the mod searches the instance folder for folders that contain no files and deletes them. Folders are found through every level of nesting, so an empty folder inside another empty folder is removed as well. The search only covers the current Minecraft instance's folder, so files outside it are never touched.

Some folders should stay even when empty, and for that the mod reads an optional exclusions file named cleanup_exclusions.txt in the Minecraft folder. Each line holds one path to skip, relative to the main folder, for example saves/saves. Repeat the line for every folder that should be spared. Without the file, the mod uses no exclusions and deletes every empty folder it finds. Players who want to stop the cleanup can disable or remove the mod.

The mod is client-side only, so a server does not need it and players join without installing it. It is built for Fabric and published for 1.14 – 1.21.11 with 43 release versions; the latest Fabric file is 2 for 1.21.11, dated 2026-06-13. The code is All rights reserved and not open source.
