FULLY COMPATIBLE WITH macOS Sierra (10.12).

The real true bidirectional synchronization tool! Many other synchronization apps here use the Unix tool rsync to do their job but they can't offer bidirectional sync. Ask them before buying, you'll see!

File Synchronization synchronizes multiple pairs of folders or files. It has been designed to be easy to use: choose 2 folders to synchronize then click the Synchronize button and you're done! However, there are multiple options when your needs get a little more complicated. The interface is easy to use and the application is quick to do any synchronization that you might need.

3 different synchronization modes to use depending on what you want to achieve:
• Automatic mode: whenever the content of one of the folder you synchronize changes, the synchronization is performed so you can be sure that the 2 folders are always synchronized. You set it once and then forget about it
• Repeat mode: the synchronization is performed at a regular interval that you set in the preferences. Good when you're constantly making changes and don't want the folders to be continuously synchronized
• Manual mode: whenever you want to perform the synchronization, you select the pair in the list and click Synchronize. Ideal if you synchronize a folder that is on a remote volume that might not always be available

2 different synchronization directions:
• Bidirectional: changes in both folders that are synchronized are duplicated in both folders. Best when changes can occur in each folder that you synchronize
• Unidirectional: changes that occur in one of the folder you synchronize are duplicated in the other folder. If you want to have an exact backup of a folder, that's the synchronization mode to use. You can choose to backup the folder on the left or on the right

Preview window:
• See how many items are going to be copied and deleted and what the sizes of those items to copy and delete are
• Check what is going to happen if the synchronization is performed
• Decide which item is going to replace the other
• Remove some items from the list from being synchronized
• Delete items you don't want to be synchronized

Synchronization options for each pair:
• Select the synchronization mode
• Choose the synchronization direction of that pair
• Set filters to ignore certain items
• Decide what happens with orphaned files and recently modified files
• Ignore warnings when both copies of the same file have been modified since the last synchronization
• Include or not invisible items
• See the status of the last synchronization session and when it was last synchronized

Multiple sources for the synchronization:
• Local disks
• Remote volumes shared by another Mac on your network or by a Windows computer
• USB flash drive
• Store login information for remote volumes so that they can be automatically mounted the next time they are needed
• Any volume you can access in the Finder can be used

Additional information:
• Can generate a log each time a synchronization is performed
• Error reporting gives you a description of an error so you can fix it
• Hierarchical views show you exactly where an item is in any list. Double-click an item and it will be selected in the Finder

Release Notes:

• Fixes a bug that would occur with a uni-directional synchronization on certain type of disk where when the copy would be performed, File Synchronization would invert the source and the destination in the progress dialog

• Fixes a display problem where the progress dialog would get random lines of text in it if you are using a mouse with a scroll wheel and would scroll the list of pairs under the progress dialog

• Fixes a problem where if you were to perform a synchronization and nothing would need to be replaced, the last synchronization date would not be updated

Review by DJ Trixter

Best file sync app yet! - I am a DJ and use 4 different computers on my network and I only download and update music on one computer but wanted to mimic certain folders on all my machines without using Air Drop, manual networking file transfers, etc. This app is awesome to say the least! It's uni-directional feature is unparalleled! I update folders with files from other machines and it clones them completely on all other computers no matter which computer I'm updating. Great app and for the money, it's unbeatable! Thx

It will corrupt your data - OS X has files that are called packages. They consist of components which are actually files themselves. As a user, you don't need to know that. The Finder shows a package as a single file and treats it as if it was an indivisible unit. If, for instance, you make a copy of the package file, you get all the components. The apps that store their data in these packages work on the individual components, possibly changing some, adding some and deleting some. The app, of course, makes sure that all the components always relate to each other properly when the package is closed. Repeating, if you make a copy of the package file, you get all the components at once and they are consistent because the app left them that way. When a file sync is done, it's important that a package be treated as a unit, the same way that the file system treats it as a unit. File Synchronization does not do that. It works on components as if they were indvidual files. Most of the time, there's no problem but there are circumstances where it is not. When I bought File Synchronization, I was suspicious of its behavior. I made a simple test, doing things that any of us might do in normal use of a pair of computers, and the program left me with inconsistent packages. I did contact the developer. He does not seem to understand the problem. I will not use this program. My data is too important to me. One last comment. If it happens to you, you will probably blame the developer of the app that stores its data in the package file. After all, how could a file sync mess up the data inside a file?

A Full-featured Sync Solution - Other reviewers notwithstanding, it needs emphasis that most users just want an App that works to relieve their lives of mundane repeated procedures. Nemesys developer Laurent Daudelin delivers a fine tool for syncing files across platforms. I’ve used several other file synchronization products on Mac and PC hardware with exceedingly poor results (Unix is an exception, with built-in script tools if you know how to use them). I needed a good tool to sync a 16GB flash drive between my Mac at home and my Windows 7 PC at work. As an educator who teaches up to four different classes at a time, you can imagine my need to keep test, presentation, and grading files in sync. Also, I never know which classroom I may be in, and so idiosynchracies between PCs could be problematic. But File Synchronization works without a hitch. It's robust, conceptually easy for first-time users to understand, and great quality for the money. Buying this software was a good investment.

Review by DaBunkster

Works For My Needs! - My setup is simple: Have a portable Solid State Drive that I wish to carry my media (TV Show, Movies, etc) during travel. I setup a sync between my home media drive and my portable media drive. So, anytime I add or delete movies from my home media drive, the changes are replicated on my travel media drive. Simple, supported, works and is much cheaper then other options out there.

Review by funes el memorioso

Not useful if you add files to one folder - This application purports full bi-directional sync, but it is hobbled by the fact that this is only true with files that have been recently modified. If you happen to add a file to one folder that has not been modified since the last sync, then that file will simply be deleted by the program as an "orphan" without so much as a dialog box or warning message. (Even when the warning message is enabled in the preferences menu.) If you're planning on syncing files one way, the program works well. And if you're planning on just trying to keep two sets of the same files in sync between folders, without ever adding new files to one of those folders, then it will also work for you. But this is not what I understood when I read about a true bi-directional sync. I found another program on the app store that offers a free version and an upgrade to pro at the same cost as this one. It achieves the true bi-driectional sync, includes a saved folder for deleted files in case something goes wrong, and runs in the tray much more inconspicuously than this one--a behavior I prefer. The other may have problems that I'm not yet aware of but, of the two, it's far closer to what I was looking for.

Review by Carnac12

Excellent except one BIG problem! - I like this app and, for $8 I am still using it despite a BIG flaw. I use the app for 2-way file sync between my Mac and an SD chip. If new files appear on either device, they are copied to the other. If a file is modified on either device, it is copied to the other. If a file is deleted on either device, it is deleted from the other. Great so far -exactly what I was looking for. The BIG flaw is that if an old file is added to a folder, or moved to a different folder, instead of adding the file to the corresponding folder on the other device, the app mistakenly deletes the file from source device! The app mistakenly decides the old file has no corresponding match because the corresponding match was deleted, and then it deletes the source file!!! There is an excellent preview feature which is the saving grace. You can use Preview to check for this bug before commiting to a sync.
