Awesome!! I have been looking for an application like this for months!! Finally I found something that can efficiently manage all my folders (photos, music, text files, applications, etc.) which I am constantly editing and for which I need to create backups for on my laptop, ipad, 2 external hard drives and virtual hard drives such as icloud, dropbox, google drive, one drive etc.
This software is simple and easy to use, has important necessary features and best of all is quick for syncing between all these devices. Highly recommended!

Excellent freeware product, allowing you to keep an up to date backup of your files. A perfect free replacement to BeyondCompare.

This program already helped me a lot, and I am not even using it to its full potential. I like how 'close to the user' the interaction with the files is. At every point in time I know exactly what the program does. When it comes to the safety of my files, this is how I want it to be. Thank you very much!
