A free program for Android, by QNAP.

The free Qfile app lets you browse and manage the files stored on your QNAP NAS. It’s the perfect tool for anyone who wants to access files stored on a remote computer or storage device, even if it’s not connected to the internet. The app can be downloaded to any Android device that’s running the app, and it works with both Android tablets and Android smartphones.

It works by first downloading the necessary files from the server, and then allowing you to view them on your device. The app will also let you upload files to the server, or to a specific folder, and you can even share your files with other people. It’s very easy to use, and it doesn’t require any extra hardware or software.
