Half-Life Deathmatch: Source NAV Meshes

Credit to Valve for the Maps!
I simply used nav_generate in the Console, which probably will save your time from having to generate the navigation meshes yourself, right?
This DOES require Half-Life Deathmatch: Source for the maps!
Do not reupload without my authorization. Thanks!

Go to This Pc > Windows(C:\) > Program Files(x86) > Steam > Steamapps > Common > Garry's Mod > garrysmod > Addons, and in Addons there should be a file named "half-life_deathmatch_source_nav_meshes_716721634.gma" Copy that file to Desktop.
Then create a New Folder to Desktop by right clicking and selecting New > New Folder.
Open the Gmad Extractor. In the Gmad Extractor click Open, then click Browse, then click Desktop and find the .gma file, Click it then click "Open" or "Ok". The .gma file should appear in the Gmad Extractor. Click on it and then click Select then click "Extract All" and extract the files to the folder that you created earlier. Open the folder with the files in it. In the folder there should be a Maps folder. Click on it. Then you should see files ending with .nav(Those are the nav meshes). Drag them to the Desktop. Then go back to the Garry's Mod directory. Once you're there, go to Maps and place the .nav files in there.
