**Inheritance:**
java.lang.Object

**All Implemented Interfaces:**
java.io.Closeable
```
public abstract class FileSystem implements Closeable
```

File system encapsulation. Aspose.3D will use this to read/write dependencies. **Example:** The following code shows how to import file, and provide dependent files in a given directory

```
var inputFile = "input.fbx";
     var format = FileFormat.detect(inputFile);
     //create a load options instance and specify a zip file system
     var opt = format.createLoadOptions();
     opt.setFileSystem(new LocalFileSystem("textures/"));
     //load the file
     var scene = Scene.fromFile(inputFile, opt);
```
