File compression isn't just for desktops and laptops. Android devices can benefit from ZIP files too.

An Android mobile device is somewhat like a highly portable computer. As with computers, your Android phone and tablet can open rar files. Here's how to do it.

When you "zip" a file, you'll compress its data and reduce how much space it takes up on your computer or phone.

To unzip a file on your computer or phone, you can use tools that come pre-installed on the device. In some cases, using a third-party app might help.
