FileSync provides selectable synchronization of files or folders to networked Macs, external drives, USB flash drives and mounted disk images. FileSync updates recently modified files any "lone" files between Master and Copy locations. A "mirror" option is provided that only updates with the Master's file structure and moves all "lone" files on the Copy location into the Trash. A progress window shows files updated during synchronization. A handy drawer allows storage for many synchronization lists. FileSync is universal binary.

We have two mac i.e. (Imac & Macbook). I need to sync the data of both of them.

Yesterday I had download File Synchronization Software from your website. It’s really Nice to operate and Its works fine to sync the Folder data in between two mac machines. i.e. Documents, Desktop, My Picture, etc

But I face one problem, that I need to know how to sync aperture library?

I tried but aperture Library is not highlighted in destination path.

Expecting your help to sort out this issue ASAP.

Working much better than the finder in copying movie files over to a hard drive attached to my router.

The finder would keep popping up at the end of the copy saying that the file is in use and cannot finish.

This app just moves through the list of files and takes care of business.

I've used numerous other sync programs but this is by far the easiest, quickest and best. A must have application.

Thank you for your review. I am a little wary of apps that haven't had an update in years and haven't had comments in months or years so although I appreciate your comment, I wish the developer would comment from time to time too. Perhaps there will be a new release to accommodate Lion when it comes out next month.

developer's comments appear to indicate this app does not do full (2-way) synchronization which results in updated equivalent directories.

Seems to be a major short-coming in a synchronization application.

This may have been true in version 1. The current 2.1 does full (2-way) synchronization by default.

Two-way synchronization may not be desirable for document package files, or instances where a Master's directory has been largely revised. The problem is old stuff coming back over from the Copy during synchronization.

The mirror option creates a "one-way" option that deletes any resources on the Copy that are not on the Master. Whether mirror option is used or not, matching files between the Master and Copy are still synchronized bidirectionally according to modification dates.

This is a wonderful program. Small, concise, and complete. Remembers a list of files to backup. This does exactly what I need.

I created a 128-bit AES encrypted sparse image on my iPod with Disk Utility and tried to sync some files to it, but it didn't work.

According to the developer

>>>>That said, FileSync DOES synchronize files it finds in the "copy" with those it sees in the "master", it compares modification dates and copies the more recently modified, whether it's on the master or the copy.

Any new files on the "master" not on the "copy" are copied to the "copy"; however new files on the "copy" are not copied to the "master". Again, another "safety" decision, I felt it important to leave the "master" alone unless it is entered as a "copy".

If you save a file and synchronize within one miniute after previously saving and synchronizing, the file will not be considered modified. I had not seen this with regular usage, but I've confirmed it can happen when testing FileSync.

FileSync looks at fle modification dates and converts them to seconds. I believe these are rounded to the nearest minute as the Finder displays them. Hence, if you save and synchronize again within one minute, the modification date looks the same.
