How to Unzip WordPress Files Before Uploading (When Needed): Step-by-Step Guide for Beginners

Are you trying to install a new WordPress theme or plugin, but you’re seeing folders inside your download and aren’t sure what to do? Don’t worry—unzipping WordPress files before uploading is easy, and it’s a common step, especially when files you download come as larger package bundles or contain helpful documentation and extra resources.

In this beginner-friendly, step-by-step guide, you’ll learn how to quickly unzip your files and upload only what your website needs. Whether you’re using Windows, Mac, or even your phone, this article will walk you through everything you need—no tech skills required!

Why Do I Need to Unzip Files Before Uploading to WordPress?

Most WordPress themes and plugins come in a single .zip file, which you can upload directly via the WordPress dashboard. However, sometimes when you buy or download from marketplaces, the file you receive contains other folders—like documentation, demo content, or multiple installation files. Uploading the whole package won’t work, and WordPress might return an error.

In these cases, you need to unzip the main package and upload only the installation .zip file for your theme or plugin.

Step-by-Step Guide: How to Unzip WordPress Files

1. Download the File

First, download the theme or plugin package to your computer or device. It will usually look like theme-package.zip or plugin-name.zip.

2. Locate the File

Open the folder where your download was saved—usually your Downloads folder.

3. Unzip the Main Package

• Windows

  • Right-click the downloaded .zip file.

  • Select Extract All….

  • Choose the destination folder and click Extract.

• Mac

  • Double-click the .zip file.

  • The folder will automatically extract to the same location.

4. Identify the Installable WordPress File

Open the unzipped package. Look for another .zip file named logically, such as theme-name.zip or plugin-name.zip. This file is what you’ll upload in WordPress.

Tip: Avoid folders labelled “Documentation,” “Licensing,” or “Demo Content”—these are not meant for uploading.

5. Upload the Correct File to WordPress

• Go to your WordPress dashboard.

• For themes:
  Appearance » Themes » Add New » Upload Theme

• For plugins:
  Plugins » Add New » Upload Plugin

• Click Browse and select the correct .zip file you found in step 4.

• Click Install Now and follow the on-screen prompts.

6. Activate and Set Up

After installation, click Activate to make the theme or plugin live on your site. Follow any setup instructions included for best results.

Common Issues & Solutions

• Error: “The package could not be installed. No valid plugins were found.”
  This usually means you tried uploading the full package, not the installable .zip. Go back and look for the correct file.

• Can’t find an installable .zip?
  Check inside folders like “Theme Files” or “Plugin Files”—sometimes they’re tucked away inside the unzipped package.

• Still zipped?
  Make sure you didn’t try to upload folders; WordPress requires a .zip archive for upload.

Tips for a Smooth Process

• Always keep a backup of your original download and unzipped files.

• Read any README or documentation files—they often contain exact instructions for installation.

• If you ever feel stuck, reach out to the theme or plugin provider’s support team.

Unzipping WordPress files before uploading isn’t just for developers—it’s a simple skill that gives you more confidence and control over your website’s design and functionality. By following these steps, you’ll spend less time troubleshooting and more time building the site you love. Happy website building!
