folder structure

         -  PolicyDetail.ts

 --Quote/
        -Services /
                  -- Policy.Service.ts

Answer 1

Imports are always relative to the current file's location. That means you have to specify how to get to PolicyDetail from Policy.Service. It would be something like this.

import { PolicyDetail } from '../../Shared/PolicyDetail';

Demistification:

1. We start from the location of Policy.Service that being the Service folder.

2. We go to the parent (../) and end up in the Quote folder.

3. From here we go once again to the parent (../) and end up in the App folder.
4. From here we have to go in to the shared folder (Shared/) and specify which file we want from it (PolicyDetail).
