Unity Blend File Auto Cleaner (Unity 6000+)

This script automatically removes Blender backup files (.blend1, .blend2, etc.) from your Unity project as soon as they are imported. It keeps your project clean by moving these unnecessary backup files to trash automatically.

Features

• Automatic Cleanup: Immediately moves .blend1, .blend2, and other Blender backup files to trash when added to project
• Startup Check: Cleans existing blend backup files when Unity starts
• Non-Invasive: Preserves original .blend files, only removes numbered backups
• No Manual Intervention: Works automatically in the background

Installation

1. Save the script as BlendFileTrashProcessor.cs
2. Place it in your project's Editor folder (create if it doesn't exist)

• Example path: Assets/Editor/BlendFileTrashProcessor.cs

3. Unity will automatically compile and activate the script

How it Works

The script uses Unity's AssetPostprocessor to monitor new file imports. When a Blender backup file (ending with .blend followed by numbers. eg model.blend1) is detected, it's automatically moved to recycle-bin.

What Gets Removed:

• .blend1
• .blend2
• .blend3
• .blend4
• .blend5
• Any .blend file with numbers at the end

What Stays:

• .blend (original Blender files remain untouched)

Requirements

• Unity 6000 or later
• Editor-only script (place in Editor folder)
