What is cPanel Disk Usage?
Disk Usage in cPanel shows you in detail how the storage space in your hosting account is being used. With this tool you can quickly see which folders or files take up the most space and decide what to clean up or optimize.
It is useful both for beginners who want a quick overview of their space and for advanced users who need detailed monitoring for large projects.
Main features of Disk Usage
1. Total space usage
-
At the top, a bar shows how much space you have used and how much remains.
-
It helps you avoid exceeding your quota, which can cause errors (e.g. failure to create an email account or install a CMS).
2. Folder breakdown
-
A list of all folders is displayed (e.g.
public_html,mail,logs). -
Next to each folder, its size is shown in MB.
-
With the icon next to it, you can open the folder in File Manager.
3. Graphical view (Tree View)
-
Shows in a tree structure where most of the data is located.
-
Very useful for spotting hidden cache files or backups that take up space.
4. Per-folder details
-
It does not always show the exact size of every file, but focuses on overall usage.
-
For exact per-file measurements, use File Manager.
Why use Disk Usage?
-
Avoiding a full disk: When the space runs out, emails, databases or the site itself may stop working.
-
Identifying problems: If you suddenly see high usage, it may be due to logs, spam emails or backups.
-
Site optimization: With fewer unnecessary files, the site runs faster and more reliably.
Practical tips
-
Clean up old files: Check the
mailfolder for spam or old emails. -
Delete temporary files: CMSs such as WordPress often keep temporary files or cache.
-
Do not store large backups in your account. Use JetBackup or download them locally.
-
Check periodically: Look at Disk Usage once a month to avoid unpleasant surprises.
Frequently Asked Questions (FAQ)
Disk Usage shows less or more space than I expect. Why?
The tool mainly shows folders and not always every individual file. For a full breakdown, use File Manager or SSH (for VPS/Dedicated).
What can I do if my space fills up?
You can delete unnecessary files, clean up your email or upgrade to a larger hosting plan.
Can I see the usage per database?
Not directly from Disk Usage. This is done through MySQL Databases or phpMyAdmin.
Conclusion
cPanel Disk Usage is an essential tool for checking the storage capacity of your account. It lets you quickly identify which folders "eat up" space, clean up and improve the performance of your website.
