FileSystemFileHandle class

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers. The interface of the File System Access API represents a handle to a file system entry. The interface is accessed through the window.showOpenFilePicker() method. Note that read and write operations depend on file-access permissions that do not persist after a page refresh if no other tabs for that origin remain open. The queryPermission method of the FileSystemHandle interface can be used to verify permission state before accessing a file.
