The getDirectoryHandle() method of the FileSystemDirectoryHandle interface returns a FileSystemDirectoryHandle for a subdirectory with the specified name within the directory handle on which the method is called.
getDirectoryHandle(name)
getDirectoryHandle(name, options)
name
A string representing the FileSystemHandle.name of the subdirectory you wish to retrieve.
options Optional
An optional object containing options for the retrieved subdirectory. Options are as follows:
create Optional
A boolean value, which defaults to false. When set to true if the directory is not found, one with the specified name will be created and returned.
A Promise which resolves with a FileSystemDirectoryHandle.
NotAllowedError DOMException
Thrown if the PermissionStatus.state for the handle is not 'granted' in readwrite mode if the create option is set to true or in read mode if the create option is set to false.
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 returned entry is a file and not a directory.
NotFoundError DOMException
Thrown if the current entry is not found or if the target directory doesn't exist and the create option is set to false.
The following example returns a directory handle with the specified name, if the directory does not exist it is created.
const dirName = "directoryToGetName";
// assuming we have a directory handle: 'currentDirHandle'
const subDir = currentDirHandle.getDirectoryHandle(dirName, { create: true });
