It's very simple

you just go to

C:\Program Files\Steam\steamapps\<your-account's-ID>\team fortress 2\tf\materials\models\weapons

Note: if these folders dont exist, create them. they have to be exactly like they are written in the above filepath!

and when you are in the weapons folder

just copy the folder from the archive to the weapons folder

make sure you are in the correct filepath!
