Web Disk Browser

Separate the interface from the storage

Web describes where an interface runs; it does not fully describe where files are stored or processed. Begin a web disk browser review by asking whether the application works with user-selected local files, its own browser-managed state, a remote service, or some combination. Draw the data flow before evaluating convenience.

Know which boundary you are testing

The MDN File System API reference distinguishes user-mediated file access and origin-private storage. It also documents secure-context and compatibility considerations. Consult the specific browser and API documentation for implementation details rather than assuming every file interface has the same support or permissions.

Use a disposable folder and clear outcomes

Test cancellation, limited selection, denied access, and an unsupported input using copied, non-sensitive material. Record which permissions were requested and what the application actually did. Test modifications separately from reading. Ask about filenames, extracted text, indexes, and network destinations as individual data-flow questions.

Review the end of the session too

Document how the application refreshes stale information, reports incomplete work, and removes retained state. Check the available revocation controls in the actual browser and application. Keep the result scoped to the tested version and configuration; a single successful review is not a universal privacy or security certification.
