Blocking a Sub Domain Directory

[is300]

[subdomain.example.com...]

How do I block this path from google without it affecting any of my other folders on both my subdomain and my main domain?

Can someone give me some direction on how my robots.txt should be configured and where I should place it.

In the root of your subdomain, put a robots.txt:

User-agent: Googlebot
Disallow: /shop/dir/camp/4/
