Version 2.9.16
Review by scanPPRCN

Must have for large file transfers and backup - I have two really great needs for this product, and it performs very well. First, I’m a semi pro photographer. I capture anywhere from 500 to 1000 photos and file per session. I need to immediately import these from the camera and then duplicate the files on other drives. Sometime after reviewing, I realize some photo need to be deleted or modified. Rather than now try to find the same files on each drive, sync folders pro does it for me. It saves hours of work. Second, I run a consulting business, where I take a data dump from the client, clean up the data and files and folders, introducing new engineerng on drawings. I copy this data structure across several drives for backup. I use sync folders pro to automate exactly which folders on each drive need to be compared and files replaced. The author is very quick to respond to questions and very helpful. Be sure to check the ? (help file) on the website so you understand what the different backup modes will do. The interface is very simple, but it doesn’t need to be anything else. It does exactly what you think it should do, plus, you can add a icon to the status bar (up top) and see the syncs that are automated, or in-process. My one bit of feedback would be to change the backup symbols to plain text or the option to change to symbols plus text so that I can be sure I selected the correct backup method.

Version 2.0
Review by TheHerdsman

Difficult to use, controls are NOT intuitive - Many of the controls are unclear or work the opposite of what's expected (for example, in the pull-down from the task bar "Auto Sync OFF" means "please turn this feature off" where most apps it would mean "this feature is currently off"). There are many more cryptic uses of terminology that makes this app not quite as useful as it should be. Some of the help screens are simply incorrect (look at A+>B and A<+B ... they say the same thing! which is it?) so you really have to guess at the developer's logic and NOT rely on Help screens. The amiguities and confusion almost led me to destroy my existing backup file-set! I realize that many of these are due to English not being the developer's native language, okay but then he/she should be a little more diligent in their Help pages! I'd rate it somewhere bertween "hate it" and "don't like it" (1.5 stars) ... I'd say "sorry I paid $8 for it".

Review by :)_

This Software is Excellent. - I recently purchased this software for their highly reasonable price on a Mac/OS 10.13.1 system with a MacBook Pro laptop computer. I have three WD Elements portable 2TB external disk drives with 1 for external production, 1 for backup of external production, and 1 for backup of the MacBook Pro. The MacBook Pro backup is using Time Machine that is part of the Mac/OS system. I use this Sync Folders Pro software to sync my production photo library that is on the external Prod hard drive for Lightroom. I then sync the Prod external drive folders to the Prod-Backup folders and then I also sync my Prod external photo library to the Creative Cloud drive for cloud backup. This software works perfectly for that as I am using the mirroring mode A=>B (A to B) that replaces the exact files with perfection of either adding or replacing files according to the last modification time stamp so that B is an exact copy of A. When I replace files on the Creative Cloud Drive, I pause the syncing function on Creative Cloud and after the Sync Folders Pro function is complete, I resume syncing on Creative Cloud Drive. Works Great.

Version 3.3.9
Review by ArthurAJ

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!

Causes system to freeze - Software was great up till the last couple months. If you are planning on using it for syncing from your local drive to an SMB I’d stay away cause it’ll most likely keep freezing your system up.

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!

Review by philrodo1

Good Synchronization app - I’ve been using the free Sync Folders app off and on for a while now. I recently needed to perform some extensive synch operations and decided to by the Pro version. It offers additional sync features that are not available in the free version. It also allows for synching folders across different volumes. If you’re looking for an app to keep your folders synchronized, this is it.
