Hi there !

I'm just wondering how much disk space ur websites are using on the server.

It says my disk usage is 7.13 Megabytes. I got 1492.87 Megabytes free.

I'm not even using 1 % of the space. My first hosting company was Hostingbay. I was on the
10mb plan. Compared to hostingbay, hostony provides so much more
space.

Any ideas how to use the free space? Could we upload anything we want to
the server?

Yes, you can upload.

Be carefull with the Terms, conditions & AUP

for time being if you want to fill up your disk space just create some good wallpapers of your site and give them as download.
Make it a high resolutions stuff and sure you will fill your hard disk in few days. I guess you might not complain laterz
