In cPanel, file usage and disk space usage are two related but distinct metrics:
File Usage:
This refers to the number of individual files stored on your hosting account. cPanel tracks how many files you have in your account, including website files, emails, databases, and other elements.
Disk Space Usage:
This refers to the total amount of storage being used on your server. It includes the size of all files, databases, email accounts, and any other data stored on the server.
Disk space usage is usually measured in megabytes (MB) or gigabytes (GB), and it represents the total storage consumed by everything on your account.
In summary:
File Usage is about how many files you have.
Disk Space Usage is about the total storage space (size) being used by all the data.
