> Controls list of extensions of files that will be included in the c#.csproj projects that Unity generates.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.3/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public static string[] projectGenerationUserExtensions { get; set; }
```

using UnityEngine;
using UnityEditor;

public class Example
{
    [MenuItem("TryMe/SetExtensions")]
    static void Doit()
    {
        EditorSettings.projectGenerationUserExtensions = new[] { "txt", "xml", ".cs", "myfunkyformat"};
    }
}
```
