This question already has an answer here:
This question was asked by Henk Straten on 5 July 2017 and answered by Zach Saucier: I have a Google Drive folder that I want to share with 2 more people. However I would like to restrict one the folders. So let's say we have John and Josh, how can I can I share the whole google drive folder with John and Josh and only a sub-folder within the drive with Josh?
My follow up question is: Can any Manager make these changes? I can add and remove members in the parent directory but the "Share" option is grayed out in the sub-directory.
