FileManager

A simple manager for selecting directories and files.

Usage

path = os.path.expanduser("~")  # path to the directory that will be opened in the file manager
file_manager = MDFileManager(
    exit_manager=self.exit_manager,  # function called when the user reaches directory tree root
    select_path=self.select_path,  # function called when selecting a file/directory
)
file_manager.show(path)

Warning

Be careful! To use the ‘/’ path on Android devices, you need special permissions. Therefore, you are likely to get an error.

Or with preview mode:

file_manager = MDFileManager(
    exit_manager=self.exit_manager,
    select_path=self.select_path,
    preview=True,
)

Warning

The preview mode is intended only for viewing images and will not display other types of files.
