 | [`//storage/browser/file_system/`](../../../storage/browser/file_system) contains the | 
 | rest of the browser side implementation, while | 
 | [`blink/renderer/modules/filesystem`](../../../third_party/blink/renderer/modules/filesystem) | 
 | contains the renderer side implementation and | 
 | [`blink/public/mojom/filesystem`](../../../third_party/blink/public/mojom/filesystem) |

 | [`FileSystemManagerImpl`](file_system_manager_impl.h) is the main entry point | 
 | for calls from the renderer, it mostly redirects incoming mojom calls to a | 
 | `storage::FileSystemContext` instance. |
