Hi there, I posted this on gearslutz, but I think this is a better place. Mac Pro - 2 x 2.66GHz SL 10.6.3 I have Logic 9 and all the Content/Jam Pack DVDs installed. There's a big problem on this hard drive that demands a reformat - new OS / reinstall Logic. But I don't have my Logic package, books, content with me - just a backup of the installer alone. But I have access to the raw folders in the Finder right now. Can I just manually back up these files: HD > Library > Audio > Apple Loops > Apple ??? I've done similar things with Spectrasonics SAGE folders and other plugins. Just install the program new so its creates the right folders, and if lucky drag and drop huge GB folders into the right places and they'll become active and available in the program. Will the above work? I'm probably missing other important files that say to Logic "look here to include these libraries, this is installed" sort of thing... some preference file or something? Or is this the only place Logic "looks" for extra content. Please let me know! ---- Sorry, to clarify that... I'm not talking about just jam packs, I'm talking about ALL the built in instruments, sampled sound, synths, etc. ALL the content. I have it installed now. I've found a 31 GB folder (the path I listed above) Is that everything? And is it even possible? My brother has all the content DVDs for Logic at the other end of the country. Do I have to get them back? Or since they're installed right now, can I manually copy them to a backup hard drive, reinstall Logic with just the 1st disk, and then copy them back? Sorry to be redundent, just want to be clear Thanks for any help.
