 - The [File Handling API](https://developer.chrome.com/en/articles/file-handling/).
 
 Each handle provides its own functionality and there are a few differences depending on which one you are using (see the [interfaces](#interfaces) section for specific details). You then can access file data, or information (including children) of the directory selected. This API opens up potential functionality the web has been lacking. Still, security has been of utmost concern when designing the API, and access to file/directory data is disallowed unless the user specifically permits it (note that this is not the case with the [Origin private file system](#origin_private_file_system), because it is not visible to the user).

+  - : Provides a handle to a file system directory.
 - {{domxref("FileSystemSyncAccessHandle")}}
   - : Provides a synchronous handle to a file system entry, which operates in-place on a single file on disk. The synchronous nature of the file reads and writes allows for higher performance for critical methods in contexts where asynchronous operations come with high overhead, e.g., [WebAssembly](/en-US/docs/WebAssembly). This class is only accessible inside dedicated [Web Workers](/en-US/docs/Web/API/Web_Workers_API) for files within the [origin private file system](#origin_private_file_system).

+- {{domxref("StorageManager.getDirectory()")}}
+  - : Used to obtain a reference to a {{domxref("FileSystemDirectoryHandle")}} object allowing access to a directory and its contents, stored in the [origin private file system](/en-US/docs/Web/API/File_System_API/Origin_private_file_system). Returns a {{jsxref('Promise')}} that fulfills with a {{domxref("FileSystemDirectoryHandle")}} object.
