Something seems wrong there. However if using ditto works for you,
then that's fine.
I haven't done much with copying files. Moving them is very fast using
the rename command, but copying is different. If the files are small
you could try:
  put URL ("binfile:" & tOriginalFile) into URL ("binfile:" & tNewFile)
but if they are larger than a few MB, that might not be so good as it
reads the entire file into memory before writing it out again.

"cr" is defined in Rev. I prefer using it instead of "return" because
"return" also means return a value from a function and I prefer to
make sure they are obviously different. And it's shorter to type :-)
