Learning how to use Zip files is a great way to save space on your computer. You need to be familiar with the Zip format since it allows you to compress files by up to 80 percent of their original size. Each OS has a different procedure of how to convert files to Zip format. In this article, we'll look at what Zip files are exactly, and how you can convert your large files to Zip format and save space on your device.

What is a Zip file?

A ZIP file is just a compressed version of the same file. When you zip a file, you can save data storage space. It can be reduced up to 80 percent.

Zipping files refer to the act of compressing the file, such that all photos, documents, videos, and audio files have been squeezed together to occupy the least amount of space on your hard drive. Most documents do not take up a lot of space unless they have charts and images in them. Here are some significant reasons why Zip files exist:

  • To save space: Compressed files are useful because they help you save some significant hard drive space. This is because zipped files condense content to just several megabytes or kilobytes. It's quite appropriate for storing large files on your system without worrying about running out of storage space.
  • Faster emailing: The primary reason to compress files is to help you send them faster via email. Larger files take a lot of time to attach in an email, so zipping the files saves you both time and space, as well as bandwidth.
  • File security: File zipping helps encrypt sensitive files that you need to send through emails. It is especially key to keep your files secure and away from prying eyes on your device. You can also introduce other security measures, such as the use of passwords, to protect zipped files.

How to save a Zip file

On Windows, the easiest is to right-click on the home screen on the desktop of your computer. This will give you a drop-down menu with an option that reads 'Compressed (zipped) folder." This will create a new folder with a zipper icon on it. After creating your new zipped folder, you can rename it appropriately then drag and drop files into it. This process applies to small files but differs for larger folders or files.

The process is slightly different on Mac:

  • Right-click on the file you'd like to zip.
  • Choose the option labeled 'Create archive of (file name)'
  • The file will be saved as a zip file with a .zip file extension.

  • Move the cursor to the file or folder you need to compress and left-click on it once.
  • A Finder menu will appear. Select the option marked 'File' and another drop-down menu will appear. Scroll down the menu until you see an option marked 'Create Archive of (file name)'.
  • The file will be compressed to a zip file, and it will appear on your desktop.
