The getFileHandle() method of the FileSystemDirectoryHandle interface returns a FileSystemFileHandle for a file with the specified name, within the directory the method is called.

name

A string representing the FileSystemHandle.name of the file you wish to retrieve.

options Optional

An object with the following properties:

create

A Boolean. Default false. When set to true if the file is not found, one with the specified name will be created and returned.

A Promise which resolves with a FileSystemFileHandle.

NotAllowedError DOMException

Thrown if PermissionStatus is not 'granted'.

TypeError

Thrown if the name specified is not a valid string or contains characters that would interfere with the native file system

TypeMismatchError DOMException

Thrown if the named entry is a directory and not a file.

NotFoundError DOMException

Thrown if file doesn't exist and the create option is set to false.

The following example returns a file handle with the specified name, if the file does not exist it is created.

// assuming we have a directory handle: 'currentDirHandle'
const fileHandle = currentDirHandle.getFileHandle(fileName, { create: true });
