I'm testing out this product in hopes that it can replace the "File Synchronization" that I currently use. I don't really like the way it syncs Keynote files. I understand that Keynote files are package files. If I am working on a 100+ slide file (sometimes upwards of 500MB w/ photos) and out of habit hit save at the end, it updates the modification date. There have been an occasion when I hit save, but there were actually no changed slides in the file. "File Synchronization" updates the entire Keynote file, even though all individual components are identical.

I'd like to find a program that can peak in the contents and only update those changed pieces (and maybe the folder itself so that it's modification date matches).

I tried testing SyncTwoFolders by creating a 4 slide file, syncing, then editing 1 slide on the original, then syncing again. Several times now, it has damaged the keynote file on the Target drive and the file will not open.

I have Settings set to "Reciprocal" and "Manage Dates" with preferences unchecked for "Package" and "With extension".

I couldn't find an email for the developer on his site (could only read the English portions of the site) and thought I'd try here.

Any ideas? Am I going about this the right way? Is what I'm trying to accomplish possible?
