Question : Problem: How to move ITUNES library to another drive on same PC

How can I move my ITUNES library to another drive?  It is on my C Drive, which is practically full, but my D Drive has tons and tons of space.  

I tried to move one album.  It is still visible from ITUNES, but when I try to play it, it tells me the songs are not there and asks me to locate them.

I have about 350 albums, so I can't do this for every song on every album.

Answer : Problem: How to move ITUNES library to another drive on same PC

It means ALL the music from ITunes in you computer will be moved to the folder specified as the default folder for Itunes Library, normally "C:\Mydocuments\Mymusic\ITunes\ITunesmusic"
but if you follow the previous instructions it will be "D:\MyMusic"
Other posibility is
To Move your music to "D:\MyMusic" using the Explorer
Open ITunes
Mark all of your songs
Delete them
The previous step is to clean ITunes so you won't have repeted entries and won't ask you to find the files you moved.
In ITunes
ºFile
ºAdd Folder to Library
   Chose d:\MyMusic
That way you know where your music is and also ITunes
You should sincronize your IPod after moving the music.
