This is a quick and easy tutorial for changing storage space quotas on specific cPanel accounts. This process is done in WHM, which is the GUI interface for managing all the accounts on cPanel. Once logged in you can click List Accounts under Top Tools on the main screen.
This will allow you to search for the account you need. You can search by the username or domain as shown below.
From there click on the + to the left of the domain and you will see a series of actions, including a blue Change Quota button. Click on it.
From there you can change the quota to the appropriate size and save it.
Now the account should have enough storage. We often build in a hard cap for storage, something like 1 or 2 GBs to avoid using up a server’s space too quickly. But this feature allows a quick override for special instances, which can be useful when a student, staff, or faculty member simply needs more space.
