I had a powerbook 17" 1.67 with 120 GB and installed FCP Studio with all its libraries, and it almost filled up my hard drive. I was pretty displeased, since I use my laptop more than just use it for FCP. So, I sold my Powerbook and bought a Macbook Pro 17" 2.33 Ghz IC2D with a hard drive of 160 GB. I just don't want to fill my hard drive with the applications. Now here are the facts: I have a 250 GB external Hard Drive. I guess I cannot install FC Studio in the external HD, but while the box reads that the programs take only about 4 GB of space which is not bad at all) the libraries associated with it will swamp 42 GB of space, and those, I would love to get them off my laptop. Is there any way to customize the installation so I will only install the programs and diet those 42 GB in my external HD? Thanks to all!
