Exactly what i was looking for!
I always wanted to take my iPhoto/Photos collection and keep it in sync with a folder structure for backup purposes and in case iPhoto/Photos ever became corrupted (it’s happened before). I knew you can export from iPhoto/Photos but it was a manual process and I would either have to know which changes I made and only export those, or export everything again (over 300gb of photos). So when i found this program i was hoping it would be what i was looking for and it is exactly what i was looking for. I can now setup multiple sync connections and have only the changes sync. If your looking to keep your iPhoto/Photos collection in sync with a file structure, this is the program for you. FYI, its a one way sync, from iPhoto/Photos to your file structure.
