Remove or don't create empty folders

[JimKnecht]

Here is how I am using HBD.

1. I download the files on a windows laptop I use most of the time
2. then I copy the downloaded files to a remote storage drive on my Mac
3. I delete the files from the laptop but leave the cache file
4. when I rerun the HBD it will create empty folders for ones I have already downloaded and moved to the other computer/drive

The network share isn't always connected for various reasons so that is why I dl to the laptop drive. Anyway t would be nice if there were only folders for new and updated things rather then all of them, currently that is 173 folders and only a small percent have anything.

I know my use case is different from most bit it would be a nice feature.
