I have 4 computers that syncs my files with a NFS location. On Windows I used SyncToy and it does what I exactly needed. If any file gets updated on any location, 4 of them gets updated.
Now with this application I don't think it's doing what I want it to do. For example I have a file in both Location A and B and I deleted it from location B, now location A should delete it too, which I run synchronization. But it copies the file from location A to location B. But I don't want to file, that is why I deleted it. So I think you have to make me understand how it actually works.
