If you don't want to fill your local machine with files from a production/stage/dev environment you can instead serve them from production through a proxy.
- Enable the Stage File Proxy Module
- Go to the configuration menu for the module at Configuration / System / Stage File Proxy Settings
- Under the origin website put the url of the website you wish to pull files from.
- Clear cache and refresh your page and you should now see files being served from your production website.
