Robocopy is not a VFP command, it's a Windows command-line utility that you execute from a CMD window. It's included by default in Vista and later, and available via download for XP.

You can use the VFP RUN command to run this utility, or the ShellExecute API. If you do this you may need to explicitly call the command processor e.g.

lcCommand = "CMD.EXE /C ROBOCOPY C:\work C:\destination /move /minage:14"

RUN &lcCommand

You can achieve what you want to do with pure VFP, using ADIR() etc. but it takes more work.
