Sync Folders Free synchronizes folders on-the-fly whenever there are changes, when connecting external drives, or manually. The application synchronizes folders with or without filters for folder names and / or file names. The Sync Folders Free is perfect for backing up to USB, to memory cards, or to disks on remote computers on your network.

Warning! Version 2.x is a new application vs version 1.x from a technical point of view. Completely changed the core of the application and algorithm of comparison of files structure which increased the speed of comparing 4-10 times for folders with many files and improved more...

I have used this for a few jobs. It appears to be stable and efficient. I have not noticed the memory leak some have described. The documentation is definitely confusing. I can't say for sure but it appears to me that this may well be the best sync program on the market. Too bad the documentation is so poorly done. I have emailed the developers to see if they can fix the audio problem on You Tube.

Definitely misleading in a number description points. Needs clarification from the developer.

I tried Sync Folder Free..on OS X Lion. But I don't know why program become unresponsive everytime I try to sync. And 'Activity Monitor' show very high memory usage nearly 1.4 gigs. which chokes my whole machine...only 'Force Quit' is the option left for me.

It would sure be nice to know if this can sync folders between computers over an AirPort Extreme WiFi connection, or over the Internet. And it would be nice to know what the differences are between the Pro and free versions. If the developer won’t make the effort to clearly describe his/her app on sites such as MacUpdate, I’m sure not going to make the effort to find out myself by downloading and trying it.

It seems, that this Tool is NOT free.
In the App Store (found it on their website) the app costs US$ 5.99

I believe that price is for 'Sync Folders Pro,' which is not the same as 'Sync Folders Free.' I'm not sure what the difference is, though.


There is a difference between the free and the pro, according to the developers:

- Sync *any number* of folders on your Mac same time for Sync Folders Pro.

 - *Schedule* synchronization folder Mac for any time for Sync Folders Pro.
- *6 modes* of synchronizing for Sync Folders Pro.


Gregm Thanks for sharing.


Thanks to Gregm for posting the developer’s description of the differences between the free and pro versions, but I cannot understand the developer’s English in that description, so I still don’t understand the differences.
