This module is a great feature for all users to keep track of their bandwidth and disk space usages. Everyone hates paying overage fees, whether it's for your cell phone or your website. This module makes it clear what space is being used and it's also a great way to monitor the activity on your site.
My favourite thing about this module:
I really like that it lists your disk space usage by folders so you can see what is taking up a lot of space. It is also convenient to view your bandwidth usage by month so that you can compare.
