# Sandbox.Scene.ISceneEditorSession.TransientFilesystem

```csharp
BaseFileSystem TransientFilesystem { get; set; }
```

Get the filesystem in which temporary files can be created. These files can be used (and shipped) by a package, but won't be stored in source control.
This is usually used for files that are expected to be re-generated at runtime by the package itself.

Declared in [Sandbox.Scene.ISceneEditorSession](/api/Sandbox.Scene.ISceneEditorSession).
Assembly: `Sandbox.Engine`.
