Hi, I have a normal site on a host with cpanel and the basics and I want to make a subdomain for 1 of my members to have their own little site. But how will I make this folder limited so they dont take up all my space?

Is there any way I can limit this folder to be able to store no more than 30mb? Maybe with a hidden .file or something?

Thanks

Unfortunately, from cPanel alone you cannot do something like this. Perhaps ask your host if they would create a subdomain on your account with the specs you give them. That is the only way you could actually limit the usage.
