What is Disk Space Usage?
Disk Space Usage is the amount of space you have used with the files for your web site. When you signed up for your hosting account, you were given a specific amount of disk space that you could use. To see how much this is, check the Account & Server Stats tab on the main screen of your cPanel interface.
It is important to keep track of your disk usage as you will be unable to add more files to your site if you run out of disk space. You can use the Disk Space Usage Viewer to identify which files are taking up the most space in your account. If those files are no longer needed, you can delete them in the File Manager to free up some space to add more files.
