Thanks Chuck, I think I'll just go the rsync route. I'm very familiar with it. I don't particularly want to install it on the boxes I'm concerned with momentarily, but I know how it works. Your other option seems intriguing, but I'd rather not install more software on these boxes if possible. I was hoping for a magical, don't have to install anything-type solution :) Perhaps I left out an important piece... even though I'm copying directory structures, in many cases the bulk of the data will be contained within massively large individual files. (Hence why rsync wasn't my original choice). Steve
