How to use cPanel Disk Usage tool to clean up server space is a question every growing business eventually asks.

For many myglobalHOST users, the fear isn’t just the lack of space—it’s the risk of your website crashing or your business emails bouncing.
Fortunately, the cPanel Disk Usage tool is an incredible feature designed to help you find and destroy “space-hogging” files in seconds. In this guide, we will walk through the effortless process of auditing your storage and reclaiming your server performance with total confidence.

-
Storage Overages: Prevents extra billing by keeping you within your Cheap Web Hosting limits.

5 Effortless Steps to Clean Up Server Space Using cPanel
1. Accessing the “Disk Usage” Dashboard
To begin, log in to your cPanel dashboard. Under the Files section, click on the Disk Usage icon. Unlike the standard File Manager, this tool provides a high-level graphical overview of your entire account. It is the fastest way to see if the problem lies in your website files, your databases, or your email accounts.
2. Identifying the “Space Hogs”
Scroll past the bar graphs to the bottom of the page where you see the collapsible directory list. This is the secret weapon for server cleanup. Sort the list by Disk Usage (Size) rather than Name. This instantly brings the largest folders—often public_html, mail, or tmp—to the top of your view.
3. Deep-Diving into Sub-Directories
The cPanel Disk Usage tool allows you to click the “>” arrow next to any folder. This reveals exactly which sub-directory is the culprit. For example, you might find that wp-content/uploads is huge because of unoptimized images, or that an old /backup/ folder from 2024 is still taking up 5GB of space.
4. Taking Instant Action in File Manager
Once you identify a non-essential large folder, clicking the folder name will instantly launch the File Manager in a new tab. From here, you can delete the files.
Power Tip: If you want to reclaim space immediately, make sure to check the box “Skip the trash and permanently delete the files” when prompted.
5. Managing Gargantuan Email Storage
Often, it isn’t the website that’s full—it’s the email. If the Disk Usage tool shows high usage in the mail directory, use the cPanel Email Disk Usage tool to clear out old “Trash” or “Sent” messages that are older than one year. This is a powerful way to clear gigabytes of data without affecting your live website.

💡 Frequently Asked Questions (FAQ)
Q1: Why doesn’t my disk space update immediately after I delete files?
A1: The cPanel Disk Usage tool is often cached for performance. It may take up to 4-6 hours for the system to recalculate and show your new, lower usage.
Q2: Will deleting files in the tmp folder break my site?
A2: Generally, no. Files like Cpanel_php_sessions are temporary. However, never delete the folder itself; only the contents inside.
Q3: Can I automate this cleanup process?
A3: You can set up Cron Jobs to automatically delete logs, but it is safer to do a manual audit once a month to ensure you don’t delete important data.
Q4: Does “Softaculous” backups count toward my disk space?
