To assign a new quota, perform the following steps:
Log into WHM.
Navigate to WHM -> Account Functions -> Quota Modification.
Select the account you would like to adjust and click Modify.
Enter the new quota in the appropriate text box, in megabytes (MB), or select 'Unlimited' to grant the user unlimited disk space.
