Building the map ensures safer and smarter deletions.

This map tracks:

* Which assets are used by other assets
* Which assets are referenced inside scenes
* Which assets belong to Build Settings scenes

### What Happens When You Build the Map?

When you click **Build Map**:

* Better Delete scans your project
* It analyzes asset relationships
* A cache file is generated and saved

This cache allows faster loading in the future.

### Why Building the Map Is Important

Once the map is built, you can:

* ✅ Use the **Dependency Window** to view:
  * *Used By* (assets referencing the selected asset)
  * *Dependencies* (assets the selected asset relies on)
* 🚨 Receive alerts when trying to delete:
  * Assets used in scenes included in **Build Settings**
  * Critical references that may break your project

### When Should You Rebuild?

Rebuild the map when:

* You import a large asset pack
* You delete many assets manually
* You restructure folders significantly
* You modify Build Settings scenes
