Perhaps try browsing all files for the game Half-Life and upload any files you want to share or are missing. This is the only information we could locate:
This is basically a server tool, which has everything that you would want to do with ESF, whether its on the server side or the client side. You can search for servers and maintain easy favourites, view information, pre-enter RCON control, and do loads of other stuff. You can alter EVERY setting that is there in ESF, and the minute you change that setting, it is written to the config file immediately. It even has an easy binds editor like normal ESF and tons of other settings that you can browse through!
