Qsync Pro Android is a mobile file synchronization application developed by QNAP. It allows users to access files and folders stored on their NAS using their Android mobile device. The application requires Android 5.0 or later and a QNAP NAS running QTSor later and Qsync Central.

With Qsync Pro Android, users can pair folders on their NAS with folders on their mobile device using the Manage Paired Folders feature. The app also allows users to view the connection details of their synchronized mobile device and NAS on the Overview screen. Additionally, users can view the synchronization status of files on their mobile device on the Background Tasks screen and view files that have been successfully synchronized on the File Update Center screen.

One important note is that users can now select subfolders when adding paired folders. However, if a folder’s parent or child folder is already paired, that folder cannot be paired again. Another important note is that Qsync Android has been replaced with Qsync Pro Android.

Overall, Qsync Pro Android has a new user interface design and provides a reliable and convenient way to access and sync files on your mobile device.
