Linear Reader Mod (26.3, 1.20.1) – Shrink Massive World Saves and Free Up Disk

Linear Reader Mod reduces world save sizes by replacing standard Anvil region files with the Linear format and Zstd compression. This mod works on servers and singleplayer worlds to cut down disk usage while keeping gameplay smooth. It uses fast compression while you play, then applies deeper compression when the server is idle. It also adds safety backups and memory caching to protect your save files.

Features:

• Replaces standard Anvil region files with the Linear region file format to save disk space.
• Uses fast Zstd level 4 compression during live gameplay to keep CPU load low.
• Runs deep Zstd level 22 recompression when the server is idle to minimize storage use.
• Creates automatic backups of region files to keep world data safe.
• Keeps recently used region files in a memory cache to reduce disk reads.
• Cleans up empty and unused chunks with a safe chunk pruning system.
• Works on dedicated servers and singleplayer worlds without client requirements.

Commands:

• /linearreader export-mca start: converts linear world files back to standard mca region files.
• /linearreader benchmark: displays compression performance metrics and speed tests.
• /linearreader health: shows internal health status and runtime statistics.
