Where does FCPX store my Libraries?

This is kind of odd.

I have several libraries created in FCPX.

When I navigate on my HD via Finder, I see that some of these libraries are stored in my user account in the Movies folder on my main iMac HD.

Yet other libraries are stored on an external HD under a folder named Final Cut Pro X Libraries.

All of the libraries show up just fine, however, within the application.

I'm not really proficient yet with FCPX so I'm sure I've done something taboo when setting up my Libraries. 😊

I'd prefer to have all the libraries located in one location (the external HD).

Does anyone have an idea why FCPX would have stored libraries in different locations and how I can combine them all into one location on the same external HD?

Thanks 🙂
