For control units with a memory card installed, the contents of the card can be viewed using Manager. This view can also be used to add and remove files from the card. This may be useful when the memory card is being used to store Music on Hold or IP phone firmware files. See Embedded File Management Menu.
For non-Linux systems, the folders accessed using embedded file management are those on the SD cards installed in the control unit.
For Linux based systems, the folder path displays as disk in the embedded file manager. That path maps onto /opt/ipoffice on the server.
