How to Zip and Unzip on Your Windows 7 Computer (Part 1)

Q. My new SJU computer has the Windows 7 operating system and does not have WinZip. How do I open a “zipped” file?

A. Zip compression is now a built-in feature of the Windows 7 operating system, so the WinZip application is no longer required to zip or unzip.

To open or unzip a zip archive in Windows 7:

  1. Right-click the zip archive file.
  2. Select “Extract All…” from the pop-up menu.
  3. Specify the name and location of the folder for the extracted files.
  4. Click the “Extract” button or press the “Enter” key.
  5. If the “Show extracted files when complete” box is checked, as in the screenshot below, a new folder window will be opened to display the unzipped files.
