Make Multiple iPhoto Libraries and iPohot File Structure

Make Multiple iPhoto Libraries or Make an iPhoto Library on an
External Hard Drive
By Ed@Smalldog.com

With iPhoto 5 and 6, it's very easy to create and maintain multiple
iPhoto libraries. You might do this to keep separate personal and
business iPhoto libraries, or to keep one iPhoto library installed on
your computer's hard drive and a separate iPhoto library installed on
an external drive.

To create a new iPhoto 5 or 6 library, click on the orange iPhoto
icon and then quickly hold down the Option key. You will be prompted
to choose an iPhoto library or to create a new library. If you create
a new library and you want to switch back to the old iPhoto library,
simply hold down the Option key again when launching iPhoto.

You can also download a great shareware program called iPhoto buddy
to manage multiple iPhoto libraries. iPhoto buddy makes it very easy
to do this. You can read about it and download it here:

On the iPhoto File Structure

I could condense all my iPhoto wisdom in one sentence: for your own
benefit, please never, ever open the iPhoto folder library folder and
move files around. That's it. This is because iPhoto has to maintain
a very strict inventory of its data. The data structure is explained
here:

There really is no reason for the vast majority of users to ever open
their iPhoto library folder. That includes me!
