Okay so I use this folder comparison tool to sync files on a shared folder on my desktop with local folder on laptop. Files added, modified, whatever, just click and syncs correctly. The problem is now that I am using Picasa to "manage" my photos. If I add keywords or a caption, it doesn't update the file's modified date. Therefore, when I run a check for sync, it finds a difference in file size between the two but that is it. I don't want to guess the right way and sync them all from one computer to the other....! Is there some way to make Picassa update the file's modified date or something, or some other way to accomplish "correct" syncing?
