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.
