Compare & Sync Folders


Open the Mac App Store to buy and download apps.


Compatibility with OS X 10.11-10.7 & Retina! The 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 LARGE NUMBERS OF FILES, reliably and efficiently.

Server Comparisons

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!

Decent, filtering is buggy

I got this version because I wanted to have the preview feature compare to the sync pro version.
The filters are not working properly and the syntax is quite bad (even for someone with a programming background). I used the exact filter from the website for filtering of the files and it still didn't work. It needs much better support for system files. DS_Store, Thumbs.db, etcAlso I was not able to get filtering to work for apps and packages properly.
The in-app purchases werebuggy and had to reset a couple of time to work.
I'm looking for better options but so far this is actually the best one I have found which theoretically has the feature I am looking for.
