Compressing files from CD

Question

How do I compress files that I've saved to iTunes from CD? They are taking up lots of space on the iPod.

Answer 1

You need to convert them to a different format then update your iPod. Converting creates duplicate files in iTunes so you will either have to delete the larger ones or alternatively create a playlist specifically for the iPod that contains the compressed ones. If you go for a playlist, the simplest thing to do to manage the iPod would be to change the update setting to "automatically update selected playlists only" and select your list of compressed songs:

For info:
The iPod offers three ways to transfer music from your computer. You can select one of the following update modes from the iPod Preferences menu in iTunes (Edit=>Preferences=>'iPod' tab):
1) Automatically update all songs and playlists. This is the default mode, in which your entire music library, including playlists, is automatically synced to your iPod. If the music library on your computer exceeds the iPod storage capacity, you are prompted to select a different update method.
2) Automatically update selected playlists only. With this option, iTunes automatically copies the playlists you have selected to the iPod when you connect it to the computer.
3) Manually manage songs and playlists. You can also choose to transfer music to the iPod manually. This allows you to drag and drop individual songs and playlists from iTunes to the iPod.
