I have a script that is not deleting empty folders on the right side. My script is like this:

load "My Session"
sync mirror:left->right

The left side is an FTP site and the right side is a local NTFS disk.

When I run the session in the GUI, it deletes the empty folders on the right, but this doesn't work when I run the script.

Perhaps I'm doing something wrong as this is my first script and I understand that the Sync script command is still in beta.

Also, what is the difference between Sync Update and Sync Mirror?
