Find what is using your hosting disk space Print

Quick answer

Use Files > Disk Usage to identify the largest folders, then check mailbox and database usage separately. Preserve required data before removing files.

Applies to

Interactive Online customers with an authorized cPanel login and the relevant tool enabled. Confirm the hosting service and domain before changing files or settings.

Steps

1. Open Files > Disk Usage and compare the largest directory totals. Review the directory tree to locate the actual large folder rather than deleting by filename alone.
2. Check whether the space belongs to a live website, mail, database, cache, log or backup. Use Email Disk Usage or mailbox management for mail when available.
3. For old backup archives or staging copies, verify an independent recovery copy and confirm that no live site depends on them before removal. Use the application's own cache-cleanup controls for generated caches.
4. Recheck free space and retry the specific action that failed, such as an upload or incoming message.

Verify the result

Confirm that legitimate data remains accessible and the original task succeeds. Usage reports can update on different schedules, and freed file space does not establish that every mail/database problem is resolved.

Troubleshooting and support

If displayed totals disagree, provide support with the affected account, folder and time. Do not delete an entire mailbox, database or unfamiliar application directory to quickly lower the number. Contact support from the account that owns the service. Include the domain, the exact tool, the time and time zone, the last successful step, and a redacted error or screenshot. Leave passwords, private keys, cookies, and complete configuration files out of the ticket.

Disk quota exceeded or hosting account full

Check the whole hosting account and the specific quota reported by the failed operation. A full mailbox allocation can differ from a full hosting account. If a file-count or inode limit is shown for your service, it is separate from the number of bytes used.

1. Record the exact upload, backup, mail or application error. In Files > Disk Usage, compare the account's largest directories and available quota information.
2. Identify who owns the large data and whether the website still uses it. A directory named backup can contain the only recovery copy; a cache directory can belong to an active application. Preserve required data outside public web access before an approved cleanup.
3. For mail, use the appropriate mailbox/storage controls. For a database or application-generated data, use its supported maintenance process with an independent recovery copy. Do not remove raw database files or an entire mail directory through File Manager.
4. After the targeted cleanup or an approved quota change, allow for report refresh and retry the original task once. Confirm a saved file or accepted message rather than relying only on a lower usage display.

If usage reports disagree, a quota is unclear, or storage cannot be safely identified, contact support with the tool, redacted error, displayed quota and time. Keep private directory listings and customer files out of public screenshots.
