The GoAnywhere Director 4.6 release is due to go live in the next day or so. Among it's abundance of new features are some improvements to project exporting. We added the ability to export multiple Projects into a ZIP file. During the export process, you will be able to choose whether or not to include the folder description, folder variables and any subfolders. The resulting ZIP file can then be imported into another installation of GoAnywhere Director.
This should give you what you are looking for. I will make sure you get notified once the new release is available for download.
Thanks - Jon
