Thanks for the quick reply! This is a big help to setting up my build machine

Just one more thing: now that I've gone through the import process and my
archives directory is populated (and I've freed up the necessary space), is it
possible to start the build process where it left off? That is, can the build
process be started with the creating of the indexes (the building folder)
without having to go through another 2 days of processing? I'm using the
PagedImage component (without the cache for space reasons) and as I stated
before there are over 40200 images!

Thanks again!
