disks, trying to find the one that had that one document from way \
back when? Catalog allows you to find the file you're looking for \
without wearing out your disc drive (or your arm). Simply pop in a \
disk, drop it onto Catalog, and watch as it is indexed \u2013 \
virtually representing every file and tons of information about it. \
Then, when you want to find the file, search for it in Catalog and \
you find out exactly where it is, even if the disc isn't in your drive."

def dude2 = "Catalog isn't supposed to feel like an extension of your disc \
browsing needs \u2013 rather it seamlessly blends offline disc \
browsing into your work environment. Browsing in Catalog feels just \
like browsing in the Finder \u2013 your files are right there in \
front of you. Once you find the file you want, just look to see where \
it is, pop in that disk, and open it up. Whether you are cataloging \
your backup, your music collection, family recipes, or your super \
secret world domination plans, Catalog will work exactly how it should."
