Sync Folders Pro is an easy-to-use app for beginners, has the ability to fine-tune synchronization settings for the most exacting professionals.

Sync Folders Pro is perfect for backups to external storage devices including:
USB, memory cards, disks on remote computers within your network, folders on Cloud services (Dropbox, etc.) With each re-backup, the app finds and copies only new files and new file versions, thereby reducing backup time and extending the life of your storage devices.

The app can synchronize multiple pairs of folders at the same time "on the fly" using our "REAL TIME SYNC" technology, on a schedule or manually. The Sync Folders Pro also provides robust tools to filter files and folders so that you sync exactly what you want.

Do you have terabytes (TB) of data to sync? No problem! Sync Folders Pro has been optimized to work with extremely large number of files. Sit back and relax, your data is being automatically synced!

The app supports bidirectional synchronization!

Great program - Great price!


I was searching for a program that would enable me to back up some important files, but which were not stored on my main hard drive, which uses Time Machine for backup. I kept those files on one external disk. And, like they say, “if you only have one copy …you don’t have a backup.” So, I wanted to make two external drives serve as backups to the original drive. But I didn’t want to have to manually go through all the files to be certain that I’d copied over ALL, and any NEW files I had added.
It was then that I found "Sync Folders Pro,” (I opted for the paid version) which fit the bill perfectly. The instructions are a little confusing and require some time and effort to get the various concepts into your head. But I found that the Support for the program was excellent in that when I had some questions there were “almost immediate” answers sent to me. I was impressed!
I recommend this program to anyone who wants to sync files over two or more devices. Every imaginable way to sync is covered and a user would be hard pressed not to have satisfaction in the results.
The price is practically a “give-away.” It’s a great value for your money and it appears by the customer ratings that I’m not alone in my praise for a programming job well done. Sure! The interface could be improved, but the end result would still be the same!

Adding missing functionality to Finder

I was looking for extended functionality to add to Finder to sync folders and update existing files within complex structure, the one which is missing. Sync Folders Pro does exactly that, it allows you to assess the files within folders/subfolders, find missing or changed and then provides you with option to copy them over. This is exactly what is missing in Finder. On top of that you get extra flexibility by filtering and setting the way you want to copy files, adds granular approach to compare files. Another dimention is the ability to setup complex backup/mirroring tasks by automating the whole process, to keep them in sync at all times. A bit complex from the first look of it but at the end covers all your needs in copy and syncing. Thanks doing this!

my choice after trying 5-10 different sync softwares


I was a huge fan of Synk until they stop developing the software. Since then I’ve tried GoodSync, Synchronize X, ChronoSync, SuperDuper and at least half a dozen other until I finally found SYNC FOLDER PRO which does (almost) everything the others do.
The interfact is not very user friendly and could use an overhaul and streamlining for simplicity and ease of use but almost all the features are there (except maybe an easy way to do an incremental sync based on a date of last modification). It’s great that it’s on the app store, that it works on the background, that it’s light and it’s HUGELY POWERFUL!!!
I highly recommend this for the power user and if you are unusure you can start with the free version and see if you need the features of this Pro version.
