Knowledge Store, Project Collaboration\Document Manager and Resource\Document Manager are three separate entities - the documents may all be stored in the same manner/object in the database, but from the user's/app's perspective, they are separate - meaning:
- You won't see a project's folder structure in the Knowledge Store (interesting idea though)
- You won't see a resource's folders in the Knowledge Store
- You won't see Knowledge Store content in project or resource Document Manager structures
Also, access rights to each area are separate - if you see Knowledge Store and Project Documents, but can't see Document Manager on Resources, then you lack the necessary Resource-Documents-View right.
Also, be aware that document viewing for Projects and Knowledge Store have two levels of access rights for non-participants - both must exist for user to access if they are not Participants: For example on projects, folder or document must be marked "allow non-participant access" and User must have "Project-Documents-View" right (via instance, OBS or global). What this means is that even if one has "View all Documents" right, but is not a named participant on the project, the project's collaboration manager(s) can still hide stuff from you by unchecking the "allow non-participant access" box.
Hope this is helpful.
