I was wondering just how smart COPY is about copying files to a DVD or CD. Normally it has to update the DESCRIPT.ION file on the target, over and over for each file copied. Ideally TCC should compose copy a precomposed DESCRIPT.ION file to the DVD only once. Normally you don't want to copy a file more than once or update it on a DVD or CD. Maybe it should just treat DESCRIPT.ION as an ordinary file and copy it verbatim to the target only once.
