So I had all my iTunes files on an external hard drive called "iomega". This includes my manually organized music files as well as my library.itl files and all the associated iTunes files. The drive started giving me some problems, so I purchased a new external, which i've just named "External". I then moved everything from iomega to External and pointed iTunes to the library file on the new external. Now, I get the exclamation points next to the music files when I try to play them, because iTunes can't locate the file. I know that this is because the path to the files previously pointed to iomega and I now need it to point to External. Is there a way to just change that part of the path or do I need to just start my iTunes library over?
