To use WinSCP start VMware Player session and login as "manage" user. Switch to root user by typing "sudo su". Edit /etc/ssh/sshd_config and ensure PermitRootLogin is set to "yes". Download WinSCP from http://winscp.net/eng/download.php. Start WinSCP and use IP address of VMware Player as Host name and username "root" and I think the password is "sage".
Obviously would be better if the files were group writable by another less powerful user. Hope that helps. ps: Still not sold on this Linux under VM is faster than native Windows. Probably best forget it though.
