The requestPermission() method of the FileSystemHandle interface requests read or readwrite permissions for the file handle.

The FileSystemEntry interface's method copyTo() copies the file specified by the entry to a new location on the file system.

The FileSystemEntry interface's method getMetadata() obtains a Metadata object with information about the file system entry, such as its modification date and time and its size.

The FileSystemFileEntry interface's method file() returns a File object which can be used to read data from the file represented by the directory entry.

The requestMediaKeySystemAccess() method of the Navigator interface returns a Promise which delivers a MediaKeySystemAccess object that can be used to access a particular media key system, which can in turn be used to create keys for decrypting a media stream.

The createWritable() method of the FileSystemFileHandle interface creates a FileSystemWritableFileStream that can be used to write to a file. The method returns a Promise which resolves to this created stream.

The FileSystemDirectoryReader interface's readEntries() method retrieves the directory entries within the directory being read and delivers them in an array to a provided callback function.
