OPFS Viewer is a Chrome DevTools extension designed to provide a user-friendly interface for exploring the Origin Private File System (OPFS). By accessing the OPFS Viewer tab within Chrome DevTools, users can conveniently navigate through the OPFS of the current web application. The extension displays a well-organized file hierarchy, allowing users to download files or attempt deletion (though deletion may fail for locked files).

It's crucial to exercise caution when deleting files, as it could potentially disrupt the application's functionality. OPFS Viewer offers a straightforward way to interact with the OPFS of web applications, enhancing user control over file management.
