4 Methods to check and Monitor Disk Usage in WordPress

Posted on September 11th, 2023

A website is like a puzzle made up of various essential parts. These include server space, JavaScript, jQuery files, and media files. In one of our articles, we talk about crucial WordPress maintenance tasks. In this article, we’ll dig deep into one of them: checking our server disk usage and how to keep it from getting too heavy.

Why is this important? Well, think of it as managing limited resources. We don’t have unlimited disk space and bandwidth, so it’s crucial to keep an eye on how we use them to ensure our website runs smoothly. Regular checks can solve problems before they become major issues.

Now, let’s talk about the benefits. There are many, but here are the key ones:

  1. Efficiency: Checking our server space helps us make sure our website can store all the necessary data and files.
  2. Security: It helps us identify and remove errors and harmful files, keeping our database and space clean.
  3. Speed: A well-managed server loads faster and reduces the risk of data loss.
  4. Organization: It makes our website more organized and efficient.
  5. Accessibility: Proper management allows our website to be accessed from anywhere in the world.
  6. SEO: It contributes to better search engine optimization and increased visibility.

These benefits are vital for any website or blog. Now, let’s explore how to check our disk usage and analyze our server disk. But before we dive into that, let’s get familiar with the basics of disks and folders in WordPress.

Disk Usage in WordPress

Each WordPress website is divided into two main parts Files and Database. A combination of these data will be stored in your server space. Here you can see the folders and data allocation.

  • All the media files like images, videos, audio and documents accessed from media are typically stored in the wp-content/uploads folder.
  • All the Theme Files like PHP, CSS, and JS will typically store in the /wp-content/themes folder.
  • All the Plugin Files are typically stored in the /wp-content/plugins/ folder.
  • WordPress core or main files are typically stored in the root folder or /wp-admin folder.
