# Simplex Trimmer
\n### Effortless World Optimization for Modern Servers<\/p>\n
**Simplex Trimmer** is the ultimate administrative utility designed to reclaim disk space by intelligently removing unused chunks. Powered by the industry-standard **MCASelector** technology, it allows you to trim gigabytes of data from your world files directly in-game via a polished, immersive GUI.<\/p>\n
**Now updated for v11.0 with Scheduled Maintenance and Audio Feedback!**<\/p>\n

### \u26a0\ufe0f CRITICAL WARNING: READ BEFORE USE<\/p>\n
> **\ud83d\uded1 BACKUPS ARE MANDATORY**
\n>
\n> This plugin **permanently deletes chunk data**. Once a chunk is trimmed, it is gone forever and will be regenerated to its original seed state if visited again.
\n>
\n> * **ALWAYS** create a full backup of your world folders before running this tool.
\n> * **DO NOT** stop the server once the process has started.
\n> * The server will **restart automatically** upon completion.<\/p>\n
—<\/p>\n
### \u26a1 Key Features<\/p>\n
* **GUI-Based Management**
\n No complex command-line arguments needed. Control the entire process via a clean, intuitive inventory interface with **sound effects** and **immersive visuals**.
\n* **Scheduled Maintenance (New!)**
\n Don’t just kick players instantly. Schedule your optimization with a built-in **Countdown Timer** (Immediate, 1m, 3m, or 5m). The server will broadcast warnings and play ticking sounds to alert players.
\n* **Smart Filtering & Risk Analysis**
\n Utilizes Minecraft’s native `InhabitedTime` to distinguish between active bases and flyover terrain. Items in the GUI now display **Risk Levels** and **Potential Savings** to help you decide.
\n* **Dynamic Tool Updater**
\n The plugin automatically connects to the GitHub API to fetch the absolute latest version of the MCASelector binary, ensuring you always have the most compatible tools.
\n* **Massive Space Savings**
\n Drastically reduces world folder size (often by **40-70%**).
\n* **Safety Lock**
\n Includes aggressive chunk unloading to prevent file locks, a mandatory chat confirmation, and a countdown system to prevent data corruption.<\/p>\n

### \ud83d\udcd6 How It Works<\/p>\n
Minecraft tracks how long players spend in a chunk using a value called **InhabitedTime** (measured in ticks). Simplex Trimmer scans your region files and deletes chunks where the `InhabitedTime` is lower than your selected threshold.<\/p>\n
#### Recommended Thresholds<\/p>\n
* **30 Seconds (600 Ticks)** \u2014 *Safe*
\n Removes chunks generated by Elytra flyovers. Keeps almost everything else.
\n* **1 Minute (1200 Ticks)** \u2014 *Balanced*
\n Good for removing paths traveled briefly.
\n* **3 Minutes (3600 Ticks)** \u2014 *Moderate (New!)*
\n Bridges the gap between casual travel and short stops.
\n* **5 Minutes (6000 Ticks)** \u2014 *Aggressive*
\n Removes areas where players haven’t stopped to build or mine.
\n* **10 Minutes (12000 Ticks)** \u2014 *Very Aggressive*
\n Only keeps established bases.<\/p>\n
