Knowing how to create and open zip files on iPhone is a useful skill. It allows you to compress one or more files so they take up less space on your device or in the cloud — potentially saving you the cost of upgrading to a larger capacity iPhone or having to buy more room on iCloud.
Zip files are also easier to email since you may be able to squeeze their size below the typical 25MB attachment limit. What's more, the files you compress can be anything from documents and audio to images and videos and, since they're placed inside a single file, they start to become more manageable.
