Compare & Sync Folders

31 October 2019

File and folder comparison and synchronization.


Compare & Sync Folders has been developed with a dual purpose in mind: to be easy-to-use for beginners, but also provide the ability to fine-tune synchronization settings for the most exacting professionals. The app can synchronize multiple pairs of folders at the same time. Using a powerful preview mode, you can view the changes before sync, and change the operation with files, if required. The app also provides robust tools to filter your files and folder so that you sync exactly what you want. Do you have terabytes (TB) of data to sync? No problem! Compare & Sync Folders has been specifically optimized to work with extremely large files and data sources, reliably and efficiently. Compare & Sync Folders is perfect for backups to all media destinations: USB, memory cards, disks on remote computers within your network, and folders on Cloud services (Dropbox, etc.). Compare & Sync Folders is the real and only bidirectional synchronization app that you will ever need! Install VPN Server Configurator, and you can synchronize folders on a remote Mac from anywhere in the world! Install Sync Folders Pro, and you can synchronize folders "on-the-fly" using our real-time sync technology or by schedule!

  • Select two folders to synchronize.
  • Click "Sync" button.
For the Most Exacting Professionals:
  • Sync multiple pairs of folders in same time.

Not very useful without paying for the extra features. The label «free» is totally wrong.

A great app that works wonderfully to sync important files from my Mac to Dropbox. Takes the heartache out of using Rsync.

I’ve been looking for an app which will not just SYNC but also show me the differences found between folders. My MacBook has very little hard drive space and my goal is to update all my files on my network drives and deleted from my MacBook. SYNC doesn’t work well in this case. This app does it well and allows me to selectively backup/sync my folders/files to my network drive.

Very easy-to-use App. It is a useful tool to manage data and keep them aligned when you need to manually keep separate records and duplicate them.

Fantastico software para sincronizar las carpetas de trabajo de un equipo después de trabajar durante el fin de semana cada uno por separado. Lo hace rápido, fácil y viendo qué es lo que va a cambiar. Imprescindible si quieres sincronizar sin errores. ¡Muy fácil de comprender!

I was able to use this app to compare two folders on a Synology NAS. One was 115GB the other was 120GB. It performed as advertised. I also used it to compare and sync other local files in an effort to clean out duplicate folders without the fear of loosing data. It works well in an "out-of-the-box" setting and has a lot of advanced features I have yet to use. I found it very useful.

Please specify what in the app does not match the description.
There are all reviews of real customers. I receive a lot of customer emails and I ask some customers to share the experience of the app using on this website.

Version 1.3.5
05 January 2017
Just finished using the Compare and Sync to change OS from Windows to Mac. I was able to transfer files from Windows to Mac and compare back again with total security. This was important to me as one of my operations was transferring 705 GB of 24 MP photos migrating them to a different disk. It took less than 3 hours to transfer the 705 GB, same time as a simple transfer with the Mac, not any more, BUT I was able to compare afterwards to make sure all was okay. I also saved the painful exercise of backing up under another program before transferring which I would have done without using this program. It only took 15 minutes to compare all the files of the 705 GB originally transferred. On another note I transferred over 1700 files to a flash card being used as a USB drive in under 6 minutes. Good enough for me. Comes recommended.

I love using Compare & Sync with my Apple Clients. One of the digital agencies I service, uses a Font Folder on the Server, with all the “approved” fonts to be used by the various artists and designers. Instead of having each designer log in and find the approved ones, I use C&SF to create a local folder version of the Server Folder. When the server get’s updated with a new font, it automatically compares the local folder against the server, and boom. Synced. No hassel. They use a similar setup for “Current Approved Versions” of documentation. The moment a new version replaces an older one, all the users get the update in their local folders. Pretty awesome!

This other GreenWorldSoft App is very useful to backup documents. Save your Job works and keep your old files to feedback onto external device. Save your Personal data to another device. GoodBye rsync.... Great App for all the days.
