Q: I am having issues with the libraries and events in final cut pro

I am using Final Cut Pro X. Been using it for 3 or 4 years. I just upgraded to newest version 10.2.3 and I am using it on an iMac running El Capitan. The way the libraries is set up is very confusing to me and I cannot seem to keep track of the events and projects on individual drives. It seems all the events and projects are bundled up in libraries, but I cannot seem to see them individually on my hard drive to move them or archive them.

And they are taking up almost all my hard drive.

I am use to working with the events on a separate hard drive, but now I cannot seem to put the files on a separate hard drive.

Just looking for some tips or direction here.

Thanks!
