The file explorer lists by default all the files stored in your browser. You can see them in the browser folder. You can always rename, remove or add new files to the file explorer.

Note that clearing the browser storage will permanently delete all the solidity files you wrote. To avoid this, you can use Remixd, which enables you to store and sync files in the browser with your local computer (for more information see :doc:`../tutorial_remixd_filesystem`)

We will start by reviewing at the icons at the top left - from left to the right:

Creates a new file in the browser explorer.

Allows you to select files from the local file system and import them to the Remix browser storage.

Publishes files from the browser storage to an anonymous public gist.

Enables you to copy files from the browser storage to another instance (URL) of Remix.

Allows to use file located in your file system (see :doc:`../tutorial_remixd_filesystem`).
