Sync Folders is a free version of the popular Sync Folders Pro utility.
The app is an easy-to-use for beginners, has the ability to fine-tune synchronization settings for the most exacting professionals.

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

Update to Pro+ (website version) and create a bootable clone of your hard drive and you can use it if your main drive is crashed.

The app can synchronize two folders "on the fly" using our "REAL TIME SYNC" technology, automatically or manually. The Sync Folders 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 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!

Free Version Didn’t Meet my Needs

I downloaded and tries this but quickly realized it didn’t meet my needs. I really need to back up folders. Ocassionally I might need to go the other way but this version only synchs. Although it has a screen showing different modes, they were not available is this version. I think they might be available in the Pro version. I received an offer of a free trail of the pro version but I had alread purchased a different application and had deleted Sych Folders.

Sync's like a charm!

I’ve been using AllWay Sync for PC for quite some time and now find myself using my MacBook. I was searching for a suitable file/folder sync for Mac, when I stumbled across Sync Folders. Not expecting much, I gave it a try. At first, it didn’t seem to do anything with two picture folders that I had, so I tried something a little different. I set up a dummy folder and performed a sync between the pictures and the dummy. It worked perfectly! The fact that it took about 2 minutes to make the folders the same was a bonus. I have a 5 TB external drive with many (MANY) duplicate folders that is just waiting for me to sync them and regain space. My new GoTo folder sync tool!

Terrific program go PRO

Terrific program. I recently started using the mac for my full-time computer. I was searching for a way to keep my files backed up to multiple Storage devices. I've lost files before do to a hard drive crash and just don't want to have it happen again. This is taking all the worry out of backing up. My files are synced automatically and if something goes wrong I know everything Will be right there. Again I can't say how great this program is. Thank you!
