If your hosting account is running out of free space, it can affect your website’s operation, the creation of backups, or email delivery. This guide explains the main reasons for disk space usage and how to resolve them in the Plesk control panel.
1. Checking Disk Usage
-
Log in to Plesk.
-
Go to Resource Usage.
-
Check which sections occupy the most space: website files, databases, mail, etc.
2. Clearing Trash and Temporary Files
-
In File Manager, check the following directories:
-
/httpdocs/tmp
-
/tmp
-
/logs
-
-
Delete temporary files, cache, and old logs by selecting the required files and clicking Delete.
-
Empty the Trash folder if available.
3. Reducing Mailbox Size
-
Go to Mail → Email Accounts.
-
Check the size of each mailbox.
-
Delete old or large emails (especially with attachments) using the web interface or an email client.
4. Checking Databases
-
Go to Databases.
-
Delete unused databases.
5. Removing Unnecessary Website Files
-
Check your website directories for:
-
backup archives (*.zip, *.tar.gz)
-
test or old versions of the website
-
inactive CMS installations or leftover files after updates
-
-
Delete anything unnecessary via File Manager.
6. Using SSH for Advanced Users
Each user can connect to the hosting server via SSH (here, you could link to another guide on how to connect via SSH if available in HelpCrunch).
-
Command du -sh * — find the largest directories.
-
Command find . -type f -size +100M — find large files.
7. Switching to a Larger Plan
If space is still insufficient after cleaning, consider upgrading your hosting plan. Often, this is more cost-effective than risking your website’s functionality.
Tips
-
Regularly check your disk usage.
-
Store large archives locally or in the cloud.
