Clip Organizer does not store clips. It stores clips' keywords and keeps track of where clips are on your hard drive.
The clips on your hard drive are not "stored" in Clip Organizer, but are held in their current location, for example, the My Pictures folder or a folder you've created yourself, like C:\Photos.
What Clip Organizer does is keep a record of the location of the clips so that you can easily retrieve any clip and use it when you want to.
It also adds keywords to the clips. But the keywords are not part of the clip itself; they are stored together with the file location in Clip Organizer.
More on keywords in the next lesson.
