Our *three* chief weapons are .... Oops, wrong show. Zip (and tar + bzip2/gzip) provide at least three services: 1. aggregation 2. compression 3. integrity validation (CRC, etc.) I'm leaving off encryption, so someone else can continue with the SI gag. Some do a better job than others at letting you get to the rest of the archive if one spot is corrupted. > Basically, disk space is cheap ... True in many contexts, but not all.
