If you’re using a self-hosted www.ads-software.com installation, you’ll need to find a host that allows “unlimited” storage. Be warned that there in reality there is no such thing as “unlimited hosting”. Every host that advertises as “unlimted” has limits on everything in their TOS so don’t think that you’re going to host that much on a cheap plan. If you need that much storage space I’s suggest looking at a CDN or even Amazon cloud storage to get the bill a bit less then it would be on a standard hosting platform.
If you’re running a wordpress.com site, then you’ll need to ask on their fourms.
And I have to ask… 2,000,000,00MB of “funny”???? Exactly what do you have that’s taking up that much space??? ??
