Thanks for the response.
The option "Copy files to iTunes Media folder when adding to library" was already selected. So all my music is in the iTunes Media folder, I already checked. But I am not able to consolidate the files... when I select it and press Enter, nothing happens, then I see again and its not selected.
Also its not even possible to slecet "Organize to iTunes Media organization" its just grey.
What exactly is "consolidate files"... what happens if i just copy the whole iTunes folder without selecting "consolidate files"?
Thanks for the help!
What Consolidate does is to look at all the tracks in your library, and if it sees any that are not already in your iTunes Media folder, it puts a copy there.
If you have always had "Copy filles..." selected, and have not ever changed the Media folder or otherwise disrupted things, then you already have all your files in your media folder. In that case, Consolidate will not be necessary. Just copy your entire iTunes folder.
