What is Trim Milk?

Trim Milk is a free open-source application designed to help Unity developers optimize their game file sizes by removing unused assets and code. As Unity projects grow in scope and complexity over time, they tend to accumulate a substantial amount of unused assets, scripts, materials, prefabs, and other items that unnecessarily bloat the final build size.

Trim Milk thoroughly scans through all assets in the Unity project folder as well as loaded scenes, and uses advanced analysis to detect which items are not being referenced or used anywhere in the project. It generates a detailed list of all potential unused items, allowing developers to safely verify and bulk delete them with a single click.

Key features include:

• Deep scanning of all assets and scenes
• Advanced unused item detection algorithms
• One-click bulk deletion of thousands of unused items
• Flexible inclusion/exclusion system for fine-tuned cleaning
• Complete undo system for all deletions
• Logging and reporting to track space savings
• Automatic backups for safety
• Free and open source for transparency and community development

By quickly removing GBs worth of unused files, Trim Milk enables Unity developers to significantly reduce game install sizes without sacrificing quality or functionality. This helps them publish smaller, faster downloading games particularly well-suited for mobile and web platforms. The streamlined workflow saves hours of manual work cleaning up bloated projects.
