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
• 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
• 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
Note: if you have an issue with the new version, please contact us instead of stating that you're not pleased. We strive to make everybody happy with their purchase but we can't help if you complain here without ever contacting us! Some people obviously post comments while they're missing some important features. Let us help you. You won't have any help by posting comments here.
• 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
Ratings and Reviews
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.
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.
Works well …only one real issue
I can't get it to close without "Force Closing" it. Other than that it works as promised. No problem with adding files to one folder or the other as long as bidirectional sync is active - do this all the time. Consistently keeps most recent update.
Note for previous poster - ther is an option to delete orphans or not. Use carefully! I make sure both drives have the same files and 'delete orphans' is off. Only when I want to delete files completely do I turn on delete orphans, then the app accurately removes them from both drives.
