Comments:

Some main FTP functions can be implemented in Visual Foxpro through creating command files and running FTP.EXE utility as an external application. This program is usually installed on Windows computers as a regular part of the OS.

Nevertheless when using the Inet functions you may acquire more control comparing to the FTP.EXE option.
