If your website stops uploading files, emails stop working, or backups fail, your disk space may be full. cPanel provides several easy ways to check disk usage and identify what is consuming space.

This guide explains all methods to see disk space usage in cPanel and what to do next.

Method 1: Check Disk Usage from cPanel Dashboard (Quickest)

1. Log in to cPanel

2. On the right-hand side dashboard, look for:

   • Disk Usage

   • File Usage

3. If usage is near or at 100%, your disk is full

✅ This gives a quick overview.

Method 2: Use Disk Usage Tool (Recommended)

1. Log in to cPanel

2. Go to Files → Disk Usage

3. Wait for the scan to complete

4. Review folders using the most space, such as:

   • public_html

   • mail

   • backup

   • logs

???? The chart helps identify large directories quickly.

Method 3: Check Disk Space via File Manager

1. Go to Files → File Manager

2. Open your home directory

3. Click Settings (top right)

4. Enable Show Hidden Files

5. Look at folder sizes manually

Common large folders:

• /mail – email storage

• /backup – backups

• /public_html – website files

• /logs – error and access logs

Method 4: Check Disk Space Using Email Usage

1. Go to Email → Email Accounts

2. Check mailbox usage for each email account

3. Mailboxes at 100% can block email sending/receiving
