FTP is just File transfer Protocol software, using VUCC should start up FileZilla, a free FTP program.
You can download, and install, FileZilla separately:
Code:
https://filezilla-project.org/
You want the Client version.
Once dowloaded you start it up, enter your receivers IP address in Host, root in Username, leave the password blank, unless you've set one up, and click Quick Connect.
You should then see the files, off your PC, on the left, and the files on your VU+ on the right.
