Thanks for the reply, but I am still wondering: When I upgraded from iTunes2 to 3, iTunes 2 disappeared. I want to improve the sound quality of my collection but it will take a long period of spare time ripping sessions. I think it would be easiest to keep track of my progress by keeping the AAC files segregated. So I want to be able, at least for a while, to have seperate iTunes 3 and iTunes 4 apps and associated files peacefully co-exist on one drive/partition. How would I handle the iTunes installation to get that result? BTW, Jeremy, I have been a longtime user of your CSM's. great job! > >Message-Id: <p05210603bad563064f68@[192.168.1.101]> >Date: Wed, 30 Apr 2003 07:26:12 -0400 >From: Jeremy Kezer <itunes at kezer.net> >Subject: [iTunes] Re: iTunes4 > >Henri, > >>I'm thinking to leave my MP3 collecton alone in iTunes 3 for the >>immediate future and begin collecting AAC files in iTunes 4.
