Creates a file explorer component that allows users to browse files on the machine hosting the Gradio app. As an input component, it also allows users to select files to be used as input to a function, while as an output component, it displays selected files.


As input component: Passes the selected file or directory as a str path (relative to root) or list[str} depending on file_count

Your function should accept one of these types:
def predict(
	value: list[str] | str | None

As output component: Expects function to return a str path to a file, or list[str] consisting of paths to files.

Your function should return one of these types:
def predict(ยทยทยท) -> str | list[str] | None
	return value

Event Listeners


Event listeners allow you to respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called.

Supported Event Listeners

The FileExplorer component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Parameters table below.

Listener Description

FileExplorer.change(fn, ยทยทยท)
