System Information

The System Information application provides useful information about the NAS server's hardware model, the software version, the network settings, and the present state of the system. It also displays information about online users and provides a useful log feature.


The Dr. Asustor app scans the NAS for possible problems and suggests appropriate solutions. It is an especially useful application for inexperienced users.

Activity Monitor

Activity Monitor shows the utilization levels of the NAS server's CPU cores, memory, and network port. It also provides the usage level of all disks and a list of all running processes and resources used by system programs. We should note that the dual-core ATOM processor shows as having four cores because of its Hyper-Threading feature.

Online Help

Online Help allows you to get the help you need should you come across problems with Asustor's ADM OS.

External Devices

Access options that allow you to check and format external USB HDDs to all popular file systems, including fat32, NTFS, EXT4 and HFS+, over External Devices. You can also see all the USB printers that are connected to the NAS and control all connected UPS devices and USB Wi-Fi and Bluetooth adapters here.

File Explorer

The File Explorer app comes pre-installed and allows you to browse and manage all files on your NAS. ADM supports up to three File Explorer windows simultaneously, and you can easily make copies of files by dragging and dropping them into a different File Explorer window. With File Explorer, you are also able to mount ISO files to shared folders to make them available to client PCs.
