Concatenating files

[Geoff Canyon]

Ben Rubinstein already figured out the binary thing, but here are two other points: the size difference could be because the original files had resource forks that aren't being copied? Also, the URL method could be slow because, even though you're not copying all the URLs into a variable and then putting it into a URL, using URL commands might mean each time through the engine parses through the entire file to find "after"
