**Inheritance:**
java.lang.Object, [com.aspose.threed.FileSystem](../../com.aspose.threed/filesystem)
```
public class MemoryFileSystem extends FileSystem
```

The [MemoryFileSystem](../../com.aspose.threed/memoryfilesystem) will maps the read/write operations to memory. **Example:** The following code shows how to export file to memory, includes the dependent file by using MemoryFileSystem.

```
//create a scene with material
     Scene scene = new Scene();
     scene.getRootNode().createChildNode(new Box()).setMaterial(new LambertMaterial());
     //create a save option and specify the file system, so the dependent file will be written to memory
     var opt = FileFormat.WAVEFRONTOBJ.createSaveOptions();
     var mfs = new MemoryFileSystem();
     opt.setFileSystem(mfs);
     //obj's material file name is associated with the obj's file name, so we need a explicit name.
     opt.setFileName("test.obj");
     try (var ms = new MemoryStream())
     {
         scene.save(ms, opt);
     }
     //the test.obj was written to variable ms, and we can also get the test.mtl file content by
     var materialFile = mfs.getFileContent("test.mtl");
```
