I used both Freefilesync and Dsynchronize, and I like Dsynchronize better. Freefilesync installs stuff without asking you and I stopped using it, even though it was good. I also tried Robocopy but again, not fully what I was looking for. Now, on the same note, do you guys use a registry cleaner to clean your system and to keep it optimized? I found some good options on https://thinkmobiles.com/blog/best-registry-cleaner-tools/ but many people say that it's not really necessary. What do you think about that?
