Overview
OPFS Explorer is a Chrome DevTools extension that allows you to explore the Origin Private File System (OPFS, https://fs.spec.whatwg.org/) of a web application.
To use it, open Chrome DevTools and click on the OPFS Explorer tab. The extension will automatically analyze the OPFS of the current web application and display the file hierarchy. You can then click on any file to download its contents or delete the file (which may fail if the file is locked). Note that deleting files may cause the application to break.
You can test the extension on the demo page (https://tomayac.github.io/opfs-explorer/).
The source code is on GitHub (https://github.com/tomayac/opfs-explorer).
