This works on up to 5 computers and requires that they sign into i Tunes using the same i Tunes account.
To consolidate libraries, turn on Home Sharing on all the computers you want to merge and then drag and drop the files to the computer that will store the merged library.
The result is that you will have two copies of your files in your i Tunes library; one copy in its original location, and one in your "i Tunes music" folder.
If you choose to consolidate your i Tunes library, the result will be that you will create copies of all of the files in your library into a single folder (usually "i Tunes music") on the hard drive of the computer from which you are running i Tunes.
It leaves the file in its original location as well.
This contains all music, movies, podcasts, and TV shows.
Select the folders that you want to move from the i Tunes Music folder (this is usually the entire folder, unless you want to select only certain artists/albums) and drag them to the "Library" section of i Tunes.
Whether you have them organized in multiple folders in several locations or if you simply have a folder for music and videos, the files themselves are not located in the same folder.
Because of this, as you play audio or video through i Tunes, each file you choose (or your computer chooses if you are shuffling) will have to have i Tunes locate the file through its library to the location of the file wherever it is stored.Luckily, there are a number of methods--some free, some with small costs--that can make this process easier.Home Sharing, available in i Tunes 9 and higher, allows i Tunes libraries on the same network to copy items back and forth.If you only need to keep your music and video files in one location, having the duplicates may be excessive and thus consolidating may or may not be a good solution for you.Deleting the original files after consolidating or simply moving all music or video to one or two files may be a better solution in some cases.Not every household needs more than one computer running i Tunes.
