Hello. I have been using Aperture 2 for about 2 years now and I love its ease and organization. I am currently using a 2008 mac pro 2.8ghz 8 core model with 4gb of ram and the standard internal 320gb hard drive. I have 2 fw800 external 1tb hard drives (one is a graid, the other is seagate that i got as gift recently). I stupidly and unknowingly set by write disk for aperture on my internal and now I barely have 16gb left which is really slowing down my processing. Is there a way I can transfer my library to my external so I can free up space on my internal. Thanks.
