The ability to zip a file allows for a file that might be large in size to be shrunk down into a size that saves close to 80% of the space that it would have used without being zipped. When it is this size, sending the file over email becomes considerably easier because it fits within the size parameters. Finally, a level of security can be added–encryption to be exact–to the zipped file so that people cannot access it unless you want them to.
