What's New
Version 1.6.4:
  • 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.

Response from the developer regarding the issue I outlined below..

Since it's not fixed, if you are doing sync, be very very careful everybody because if you use USB drives and if that drive becomes not available, disconnected or whatever, you could potentially risk loss of files because they become deleted both on source and destination and go to trash bin without you knowing it (unless you have LOGING option turned on)

Here is response from Laurent. I think the issue is critical, it's unfortunate it's still not resolved after about 1 year being known. That was about the time when the problem happened and still not resolved.

RESPONSE:

---------
Hello.

Unfortunately, the issue hasn’t been fixed. We’re working on it. Stay tuned.

-Laurent.

Hmm, hope I don't double post, not sure why my post doesn't appear here.

Has the issue with the disconnected volumes been resolved?
In version 1.6.2 I had often the issue when one of the attached USB volumes became disconnected and as a result File Sync didn't see it so it has deleted files on the other paired volume.

Here is what happened:

1) Volume 1 < --> Volume 2

2) Volume 2 becomes disconnected (e.g. USB switch failure)

3) File Sync can't find the Volume 2 and displays question mark, however it continues doing it's job (There is an option to stop at error - but I didn't notice it first).

4) When the sync finishes, I look into trash bin and there are thousands of files deleted from Volume 1. Looking at the Log, I see thousands of entries saying files on Volume 1 will be deleted because file on Volume 2 no found.

This is unfortunately poorly done or what is it, I lost thousands of files by these destructive sync, till one day I discovered trash bin full of these files and log full of this mess.

If the volume is missing then why does the sync operation continue to run..

I am just wondering if this has been fixed.

Version 1.6.4 has 2 bugs, one being very serious.

Serious Bug: This only occurs when synchronizing my iTunes Library folder. Synchronization takes place, but then the dialog box changes to "Fixing Modification Dates..." and the program hangs. I've waited up to 15 minutes and this never changes. CPU usage is at a minimum. In order to get out of it I have to "Force Quit" the program. I saw something similar in version 1.6.3, but the dialog was "Fixing Permissions...". Same thing. Had to Force Quit the program. This is under OS 10.6.8 and only happens with the iTunes library folder.

Bug 2: Version 1.6.4 What's New: "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." This was not fixed.

WARNING - version 1.6.3 has a serious bug:

When syncing files, the window displays the wrong information - it has the "copy from" and "copy to" items reversed, making it appear as though you're copying in the wrong direction. The copy process is actually done correctly, but it can sure scare the hell out of you when you don't know!

I notified the developer, but their lack of concern and failure to promptly correct this is alarming.
Their response was "This is a known issue that we have already fixed. If you have purchased from the App Store, you'll have to wait a bit because there is another minor fix we want to do before submitting this update."

So rather that than release an immediate update for this critical bug, they've delayed the release so they can include a "minor fix."

Data integrity is paramount, and giving a false impression that data loss is occurring calls for IMMEDIATE action!

The more I use File Sync the more I like it. It handles all my back up needs. Sometimes I leave it to run overnight and when I get up all the hard work is done. I've never missed anything, it works like a dream (well more like while I dream ;)

For 6 years this has, together with 1 Password, been the most important utility on my Mac. Here is why:
1. You can synch to anything you can connect to. Be it across platforms f.e. beween a Windows machine and a Mac, be it via LAN, Firewire or any other connection you can make.
2. You need to run File Synchronization only on one computer. No need to install it on the other.
3. You can preview anything you do. You can see where Files are located, manually erase them if you do not want to keep it, or manually exclude one or more files from synching.
4. You can automatically exclude files you do not want, such as .db files with thumbnails of files which may be needed in Windows, but not on a Mac.
5. You can delete orphaned files automatically while excluding recently changed files so that you do not recopy files you just deleted from the other computer, but also do not delete files just generated on one.
6. You can even synch containers such as key chains. Of course you cannot synch actual database content (that would be asking a bit too much!)
7. The support is simply grand. On the few occasions when I needed him, Laurent, the author of the App, always figured out a solution for me - and always did so quickly.
There are very few Apps I could recommend with equally little reserve! One feature might be nice for the future: If Quick Look could be enabled in the preview, there would be no wish open!

I second you on everything you said! File Sync running here for about 3 years, I have been relying heavily on it for my back ups and it has never let me down. It's awesome and works for me flawlessly churning over the boring stuff while I drink tea and go shopping and I can't recommend it highly enough! Five Stars *****

PS: I wish the publisher makes a better job in describing how the application works. Basically all information about it is summarized on the FAQ page, when in fact it should be using guided help in the application Window.
Here is how the application works, summarized and squeezed into one paragraph:

I am impressed by this software for 2 reasons:
1. it has a very simple, clean and easy to use interface
2. it does exactly what it's supposed to do

I went through a number of applications and spent over 12 hours trying and testing different things. What I needed is a tool to synchronize (and backup) my multiple USB drives into a single big USB drive and keep them in sync, as I add more stuff into it.

Since the USB drives are older I can't format them using HSF/HSF+ to get them working with Super Duper. So I had to find an alternative.

My single most important criteria was simplicity of use and I wanted the tool to have an interface where it lists pairs of folders (or drives) to be backed up.

I went through following apps:
Get Backup Pro, Super Flexible Synchronizer, Backup List, Super Duper, Carbon Copy Cloner, Synkron, Goodsync, Folders Synchronizer, SynkTwoFolders, Synk Pro, Synchronize Pro, Chronosync, iBackup, JaBack , Simple Backup, Deja Vu .... and several others.

From this list 3 were top candidates. Deja Vu (failed because of miserable interface), Synkron (failed because when it was supposed to do things it froze) and File Syncrhonization (no issues but one, see below).

This software is not replacement for Super Duper or CCC. It doesn't something different and it does it well.

My only complain about this software is that it has no scheduler. Yes, you can use the iCal calendar application to create an event. That's not the point because I can create an event for any application using iCal and/or Automator. I don't like to put computer related things into my calendar, but one way around is to create a new separate calendar for this purpose.

(therefore 4 starts for features list)

Overall, I am a happy camper with this app and I can recommend.

I have recently moved from Windows to Mac when my laptop died. I was previously using Syncbackpro for Windows which cost me similar money. By comparison this is very light on features and nothing like as easy to use. Specific comments:
- When the clocks change summer/autumn I get 1hr time differences between time stamps on files. I couldn't find any easy way to handle this. The 'ignore time differences of xx minutes' option doesn't appear to do anything. It is going to be very irritating to have to rewrite all my data twice a year.
- I have a Windows partition on the Mac to run software that isn't available on Mac and as a result it creates quite a lot of data to sync to my portable backup drive. Ideally I'd like to exclude the partition from the sync and backup Windows files separately but can't find an easy way to do it. On my old software I could just check boxes against every file or folder to include/exclude items. This was very quick, easy and flexible.
- When I view the 'preview' run I would like to be able to sort the results in different ways so I can easily pick out the items I want to override. This doesn't seem to be possible.
- When I run 'preview', I can sometimes continue to run a 'synchronise' and other times the button is greyed out so I have to run the whole process again from the main 'synchronise' menu button. Irritating.
- When using the app to load my files onto the mac from the backup drive it crashed several times. It seems to run out of memory after a certain volume of data - poor design
- The tracker bar showing progress of preview or synchronise is useless so I can't tell how long it is likely to take to run.

I realise this isn't fully commercial software but it isn't free either so I think it is reasonable to make comparisons to Windows equivalents. This has a long way to go. The only upside (if I try and look positively) is that I haven't yet found anything better for mac.

Hello.

I'm sorry you had a poor experience with the software. Most users who try it usually likes it as you can see by the ratings here.

I wanted to comment on your point about the change from daylight saving time to standard daylight time. Most modern file systems these days support the notion of saving time. I would bet that this was some flash storage disk or external USB disk formatted as FAT32 that you've been having problems with. FAT32 dates from the time of DOS. If you don't know what DOS means, then you can understand it's VERY old. The acceptable modification time difference might help in this case but you have to enter something greater than 60 minutes. But this is more a clunky kludge than a real fix.

To exclude items, you have to create a filter. Same for the Synchronize button in Preview being enabled sometimes and disabled sometimes. If, during the analysis, File Synchronization determines that an operation would not succeed, it will prevent you from doing it by disabling the Synchronize button. Things that can fail include having 2 copies of the same file in each synchronized folder that have been both modified since the last synchronization. Since File Synchronization doesn't have the ability to synchronize the content of files but replaces the whole file, it will flag this as an error and won't let you synchronize to prevent loss of data. This can be overridden, if you know what you're doing, by turning on the "Ignore warning and..." checkbox.

I'm not sure why the app crashes. There are no users reporting the app crashing on a regular basis. Jumping to the conclusion that the app has a poor design is preposterous.

If you truly want support, email us and we'll be more than happy to help!

I am running file synchronization (FS) on 2 Macs on my home network. I have version /dupe problems I've been solving on the Macs and a WD MyBookWorld ethernet connected 1 TB Drive. Yesterday I was syncing two directories on the WD drive and the process went fine until after the copy portion it locked up at "fixing permissions" with the status bar at halfway. I left it overnight. No Change in the morning - I Force Quit the app and rebooted. I logged into the WD drive this morning and "unlocked" all the file folders in both Public and Download shares. I do not use the WD software. BTW running the app fom Mac Mini 2.33Ghz cpu/120 gig SSD and 2 gig Ram

Tried again - same indications

Ideas?

The new 1.6.2 update changes the way that permissions are handled. Now, File Synchronization leaves the system decides what the permissions should be for copied files. This could well be a permission problem. You might have the permission to read inside the folder where the problematic file is but you might not have the permission to write in that folder, even though you might be able to write to the file. Permissions are often complicated to understand et set correctly. It gets a little more difficult to manage when 2 different users write to the same folder on the network drive.

This could also be a problem that was fixed in the 1.6.2 update where if you are hiding the app and the synchronization finishes while the app was hidden, the progress dialog would not go away.

Finally, it could also be a problem with the media itself. How long have you used the drive and when was the last time you did check it with Disk Utility?

File Synchronization is a utility that has the ability to synchronize multiple pairs of folders or files. It has been designed to be easy to use and quick to do the job.

It was based originally on the File Synchronization tool provided by Apple with the old Mac OS, but has a few improvements and features to help get the job done quickly and efficiently.

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.
  • iDisk.
  • 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.
