I had a situation with possible corruption or deletion of a large number of files. I had a backup, but I didn't want to do a total replacement since I knew some source files had legitimately been changed since the backup was made.

I was looking at a very time-intensive task to clean everything up until I discovered this app. I used it to scan the source and backup folders. It clearly showed which files were different, giving me an option to sync in either direction or bidirectionaly for each file and/or subfolder.

I could not be happier. This app was exactly what I needed and worked perfectly. I highly recommend it!

100% Happy ⭐⭐⭐⭐⭐ 👍

My first version of this is 2.12 and it works like a charm. I was a little hesitant to choose this app reading some of the reviews of earlier versions. But, I was in a jam and needed an app with this functionality ASAP. So I gave it a try and it worked perfectly. I recomend turning off “Compare File Content” as it will greatly slow down the comparison process. Just having “Compare Modify Date” should be enough for most users like me. Thank you Yong Chen, you helped me to save the day.

Excellent App. . . Highly Recommend

I use a popular app for Windows called “Beyond Compare.” This is very similar, but much cleaner and easier to use. A real lifesaver when a large folder transfer gets inerrupted. Normally, you’d have to start over since it’s not practical to review hundreds or thousands of files to copy the remainder manually. With this app, you simply run a sync on the two folders, and your transfer picks up where it left off!
