EXS 24 Logic Sampler Users Group

Hi all.

I'm soon going to be purchasing the Vienna Symphonic Library 
(EXS24 format) and I'm going to want to store it on an external 
hard disk for instant recall into the EXS24. At the moment all my 
samples are stored on the hard disk of my Mac but there isn't 
space obviously for 90 Gigs of VSL! Do I need to create a VSL 
alias within my Sampler Instruments Folder or do I need to move 
the whole Sampler Instruments Folder to the external hard disk 
and create an alias in my emagic folder? I'm a little confused on 
this matter and any help would be greatly appreciated.

Cheers,

Nick Harvey
