If using sftp with WinSCP is still an option, but you do not want users to have SSH access, this can be achieved easily with sshd_config-settings like:
# override default of no subsystems Subsystem sftp /usr/libexec/sftp-server Match Group sftp X11Forwarding no AllowTcpForwarding no ForceCommand /usr/libexec/sftp-server Not sure if this is fits your needs though. -Urban
