The basic files explorer lists all the files stored in your browser's **browser storage**.
You can see them in the **browser** folder.
**Important Note:** Clearing the browser storage will **permanently delete** all the
solidity files stored there. This is an inherent limitation of a browser-based IDE. However, if you want to store files outside of the browser and on your computer's filesystem, use [Remixd](remixd.html) or use the [desktop version of Remix-IDE](https://github.com/ethereum/remix-desktop/releases/). RemixD enables you to have access to a selected folder on your hard drive. Remix Desktop is a version of Remix-IDE in an Electron app.
The icon marked **C.** above. Publishes all files from the browser folder to a gist. Only file in the root of **browser** will be published. Files in subfolders will not be publish to the Gist.
Gist API has changed in 2018 and **requires** users to be authenticated to be able to publish a gist.
Click [this link](https://github.com/settings/tokens) to GitHub tokens setup and select Generate new token. Then check the **Create gists** checkbox and generate a new token.
Take the token and paste it in Remix's **Settings** module in the **GitHub Access Token** section. And then click Save. Now you should be able to use the feature.
