  • File sharing – send, receive and search for files located on the server
  • Stream music with the server app and listen to it on the Nodescan client
  • Create and run a web server
  • Local network and over the web connectivity
  • Contact managing – create contact lists for easier access later on
  • Can be used on Windows, Linux and Mac
