Changing Drives in FTP on Windows

I’m ftp’ing from a unix server to a Windows 2000 server. The ftp service on the target box is set up so that the F: drive is the default home drive. I need to ftp files to the G: drive and can’t figure out a way to change drives in ftp….anyone know how? My other thought was to set up the profile of the Windows account that I’m logging in as to have it’s home drive be G:, but can’t seem to get that to work either.
