## Definition

* **Type:** Field
* **Namespace:** [UnityEditor](/engine/6000.6/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

UseArchive = 1
```

### Remarks

When this flag is set, the build system will package content into archive files with the ".archive" extension, which can improve loading performance and reduce file system overhead.

This flag is unnecessary if compression is enabled using the [\_compression](/engine/6000.6/script-reference/unityeditor/buildcontentdirectoryparameters/compression.md) field.
