I'm using iTunes on a Mac Powerbook G4. I've just downloaded a load of MP3s to the desktop. To import them into iTunes, I wanted to click and drag them onto the iTunes window. So I highlight all (Apple+a) and then un-highlight various files and folders that aren't MP3s. When I drag these onto the iTunes windows, the program starts to go crazy, seemingly downloading .wav, .mov, .aif files and more. I don't know where these are coming from. They're sound effects (bird calls?) and jazzy snippets of music, usually less than 20 seconds long. Movies are things like flowers opening and industrial scenes. Typical filename = AU000063. The directory created within iTunes is called "Movies". Thinking about it, the files are probably from the installation of World Book 2005. The movies have voice overs explaining what they are. But how have they ended-up in iTunes? Why did they choose to import at that moment? I'm 100% certain that I only highlighted the MP3 tracks, and no other folders. I've opened a terminal window and there are no hidden files/folders, apart from .DS_store and .localized. It's like dragging the files from the desktop has caused iTunes to scan the entire hard disk for files to import.
