# World File Cleaner \u2013 Automatic Save File Cleanup
\n**World File Cleaner** is a simple Fabric mod that automatically deletes unnecessary files from your world save folder when a server shuts down or a single-player world is exited, helping keep your save folder tidy and reducing disk usage.<\/p>\n
## \u2728 Features
\n– Automatically performs cleanup when a dedicated server shuts down or a single-player world is unloaded.
\n– Configurable deletion of files\/folders (e.g., logs, caches, session locks, statistics, etc.).
\n– Safe by default: only non-critical files are deleted (region files or player data will not be removed unless you configure it yourself).
\n– Supports both server and client (single-player mode).<\/p>\n
## \ud83d\udce6 Compatibility
\n– Minecraft Version: `1.21.11`

## \u26a0\ufe0f Important Notes
\n– **Always back up** your world save before using the automatic deletion feature for the first time.
\n– The mod **does not** delete the save folder itself \u2013 it only removes the specified files within it.
\n– On dedicated servers, the mod only needs to run on the server side; clients do not need to install it for the server-side cleanup to work properly.<\/p>\n
