Logic 8 can't find my audio files

Question

I recently upgraded to Logic 8 from Logic 7. When I did this, I almost completely maxed out the memory on my MacBook Pro. To make enough room for the upgrade, I moved many of my old files to an external hard drive.
When I try to open old Logic files, both those on my MacBook Pro and those from the external hard drive, Logic gives me a message that it cannot find the "_____" audio file, and prompts me to skip it or search for it manually. I'm something of a Logic novice, so I'm hoping that someone can tell me where Logic typically "stores" the audio files. Doing a search by date (trying to find the files by comparing the date of the Logic project and assuming that the audio files would be the same) turned up nothing. However, I didn't delete anything that I didn't move to the external drive. Those audio files have to be somewhere.
Can anyone tell me the file saving protocol for the audio files? I'm sure that I can find them if I can figure out where to look.
Thanks a bunch for your help (you Logic Rock Stars!)

Answer 1

When you originally recorded the songs, had you saved them as a Project? Because if you had, an audio folder for the song would have been created within the songs main folder, and that's where the audio files that are missing will be.
Because you simply dragged the Logic files over to the external drive, and then tried to open the songs, the original audio pathway is still intact, and the Logic file is looking for the audio in it's original location, which, of course, it is not now.
When you get the first message "Cannot find lead vocal 1 (or whatever it is), choose "manually", and navigate to the audio file folder of that song. Once you locate that first missing audio file, Logic will look there for the rest of the missing files, and finish loading the song correctly on it's own.
So... let me ask you... are the Logic song files themselves found with a song folder of the same name? If they are, you should also see a folder within that song folder, labeled "audio files". If that's the case, the audio for that song is stored within that audio files folder.
If you hadn't gotten into the habit of saving songs as projects from back in Logic 7, then this could be a very long, and tedious process, of locating those files.
