The most accurate method to see how much space your account is using, is to login to cPanel and click on "Disk Usage"
The Disk Usage feature lists all of the subdirectories contained within your home directory. You can click any of the listed directories to open the corresponding subdirectory in cPanel's File Manager feature. This function allows you to view specific disk usage information about individual files and directories contained within the subdirectory.
Note: The Disk Usage feature does not display disk usage information for individual files contained within your home directory. This feature also displays disk space usage summaries for:
- Files contained within your home directory
- Files in hidden subdirectories
- Mailing lists in Mailman
- Files not contained within your home directory (see Other Usage bar)
