How can 10.1 work?

Not sure how this is supposed to work . . .

I discovered to my horror that FCP X 10.1 now COPIES every clip I brig in from another Library. The popup message says that if the file is stored externally, it will be linked and not copied - that's not true on my system.

I moved my project to the Movies folder on a spare system drive that I have, to test this.

Then I rebooted into that system drive and opened the moved project.

Next, I opened a library that's on my 4TB G-Tech drive and added a 10 second chunk of one of its clips to the project storyline.

The popup message showed up, saying external media would be linked not copied, and I clicked OK.

Once the beachball stopped spinning, I selected the clip in the storyline and pressed Shift+F to be sure I had the correct clip in the browser, then I selected that and pressed Shift+Cmd+R to reveal in finder.

Guess what?

Dropping that 10 sec clip on the storyline had brought the entire 1.23 GB file onto the system drive (movies folder).

This is unworkable for me - unless someone can suggest where I'm going wrong.

I have a large number of Events with hours and hours of footage - if I put them all in one Library, the MacPro grinds nearly to a halt.

If I keep the media in different Libraries, everything will bet copied over and over again as I access different Events from different Projects.

Once more, back to the drawing board for me, I fear.
