This article describes what ZIP files are and why they're used in some situations. We'll also look at how to open one to see its contents, and how to convert the files inside to a different format ...

We show you how to open & view ZIP files on iPhone or Android Mobile. You can use built-in feature or apps like Google Files or iZip.

If you have a full, 750MB Zip drive or multiple, smaller Zip drives you want to write to a CD-ROM disk, try compressing the files first and then writing the smaller, zipped archive to the CD instead.
