Ahh, that helps (updating from tag), but there's still a problem. I'll get to that. First, I drew a diagram showing my exact setup--which I hope will make things even more clear:
The copy of Media Jukebox installed on the Surf Computer has all the local drives plus USB #1 set on Auto-Import. Whenever new files on the local drives get synchronized to USB #1, this should be reflected in Media Jukebox if Auto-Import is working.
To backup the main library on USB #1 to USB #2, simply synchronizing the folders should be enough, but I want to make sure any new information stored in the Application Data folder on Surf Computer will also show up on the Workstation Computer, so I also synchronize that as well. So when I boot up either copy of Media Jukebox with either computer, they should contain identical view/tagging/columns...etc, except on the Workstation Computer I cannot access the files in the local drives on the Surf Computer (which is fine, since I have extensive Smart Lists that exclude certain drives depending on which computer I'm using or if the USB drives are even turned on).
Ok, so the issues that remain are:
1) Let's say I changed the rating/tagging of an mp3 located on a local drive. I can see that it's been changed because the file date has been updated.
Now, if I synchronize that file to USB #1, although the mp3 file itself will save over the version on USB #1, the rating/tagging changes will not show up in Media Jukebox. So now I have an mp3 that is rated and tagged a certain way on the local drive, but rated and tagged a different way on the USB #1 drive, because Media Jukebox has not updated the rating/tagging of that file after it's been updated from the synchronization. I can go and manually find all the files I've recently synchronized and manually update them by using the "Update from Tags" option, but
what I'd really like to be able to do is to have Media Jukebox do this automatically. That, is the main problem here. If I can only get Media Jukebox to update the newly synchronized rating/tagging, all my problems will be solved.
I do have Auto-Import set to "Update for External Changes" but it doesn't seem to work. I also checked all the Standard Library Fields and they are all set to "save tagging info in physical file when possible." If those are the only settings that can get me what I need, and they aren't working properly, then it's probably a bug? Or am I missing something still (on how to do what I want Media Jukebox to do)?
BTW, thanks for the help thus far. Really appreciate it.
