Consolidating files on itunes
Considering that most people have thousands, if not tens of thousands, of songs in their i Tunes libraries, those libraries can take up a lot of hard drive space.
And when you add in apps, podcasts, HD movies and TV shows, and books, it's common for an i Tunes library to tip the scales at 25, 50, or even 100 GB.
However, before you do that, make sure that everything from your i Tunes library transferred to your external drive, or that you have a second backup, just in case.
Remember, when you delete things, they're gone forever (at least without redownloading purchases from i Cloud or hiring a drive-recovery company), so make absolutely sure you've got everything you need before you delete.
I have done this a few times for myself and a couple friends who have made the switch to Mac and always follow this method, but it wasn’t until I stumbled on a post that I realized we hadn’t covered this here before in the context of a PC to Mac switch.
If you just want to move your i Tunes library to another location on your Mac it’s a pretty similar process.
You can run out of those bytes in no time at all, especially if you fill your laptop with multimedia files like music and movies – the types of files that you keep and manage using a multimedia manager like i Tunes.
A quick look at the folder sizes inside my Mac Book hard drive shows that the i Tunes folder occupies a large area on that near-full storage space.
This is by far the easiest way to transfer an i Tunes library from Windows to OS X (and even vice versa), and it’s entirely free – there is no need to download any of the third party apps or services that claim to do it for you.To regain some room to breathe, I decided to move my collections to an external drive.
