Step 4) On the panel, head over to the console page. Only drag and drop the ones that are there.

This includes materials, models, sounds and resources, however, as said before don't worry if you don't have all of them. Step 3) Drag and drop any content folders into this directory. If you aren't sure how to connect via SFTP yet, click here! This directory includes folders such as addons, data, maps and etc. Step 2) SFTP into your server and go to the base Garry's Mod directory, which should be referenced as garrysmod. Don't worry if the addon you are trying to add to FastDL does not include all those folders it simply just means the addon doesn't use custom content for that category. These folders could range from: materials, models, sounds and resources. Step 1) Addons that have custom content will include folders that include the content. Using this system we're talking about today, clients are able to download content at standard HTTP speeds which would be significantly faster. Without FastDL, speeds are capped to 20kb/s which would mean a lot of time is spent downloading content. FastDL (Fast Download) is a system in Garry's Mod used to grab content from the server and take it across to the client faster than the default method Garry's Mod uses.
