TTT missing maps!

I added the maps for my server to my fastdl but I get the missing map error and then im kicked from the server! It’s happeneing with 80% of the maps that i use and have played on before on other servers. This is happening to anyone that joins my server as well. Is there a fix for this? Any help would be appreciated.

Did you add it via resource.addfile?

Also, what is your net_maxfilesize set to?

It’s set to 100mb. And whats resource addfile? Sorry I’m new to this. Most of the maps came with one bsp file which i put into the maps folder?
