ZIP File Uses
The most common use for ZIP files is for software downloads. Zipping a software program saves storage space on the server, decreases the time it takes for you to download it to your computer, and keeps the hundreds or thousands of files nicely organized in a single file.
Another example can be seen when downloading or sharing dozens of photos. Instead of sending each image individually over email or saving each image one by one from a website, the sender can put the files in a ZIP archive so that only one file needs to be transferred.
