This feature shows you how you are using your disk space. It can also help you manage your disk space quota by indicating files and directories that use large amounts of hard disk space. The Disk Space 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.
