Q:

Managing access control for sub-folders within a Site?

Organization wants to move a network share to SharePoint Online (OneDrive). Needs a bit of granularity WRT permissions.
Contrived example:
Blueprint Site
 -Documents
  --Project A
    --Drawings
    --Models
    --Bills of Lading
  --Project B
    --Drawings
    --Models
    --Bills of Lading

User List:

VP Engineering - needs read/write access to everything
Purchasing Mgr - needs read access to Documents/__/Drawings
Logistics Rep - needs read/write access to Documents/__/Bills of Lading

I've poked around in the advanced permissions section online. I guess my questions are as follows:

Does SP support access restrictions with this much granularity?
If yes, how would one go about setting it up? Do I need to touch each and every directory/file?
Is there a script/batch file way of setting a truckload of permissions?

Thanks for reading.

A:

Microsoft enterprise support was able to sort this out:

Open your SP site's document library  
Navigate to the folder you want to change permissions for 
Make sure you are in "Classic Sharepoint" mode (look in the far bottom left corner)
Click LIBRARY in the top ribbon
Click LIBRARY SETTINGS
Select Permissions for this document library
De-sync permissions
Grant permissions on an as-user
basis as needed
