Sync 1:1
synchronize remote -delete C:\Users\userx\Desktop\S /home/shared/userx/S
synchronize local -delete C:\Users\userx\Desktop\R /home/shared/userx/R
synchronize remote -delete C:\Users\userx\Desktop\R1 /home/shared/userx/R1
synchronize local -delete C:\Users\userx\Desktop\R2 /home/shared/userx/R2
Seems like this does the job.
