I am searching for a popular cloud-based storage solutions with flexible shared folder permissions. Here is my problem: currently, we are using Dropbox to share files among a large team (ca. 80 members). However, Dropbox's ability with regards to shared folder permissions are rather limited. (See Shared folder user permissions in Dropbox.) As a work-around we have created separate folders outside of our usual folder structure, which we are then able to share among subgroups. However, people are annoyed of the extra effort to keep things well organized.  My question is:How to use GoogleDrive, OneDrive, and box.netto allow every team member to access a folder via sharing (so it will also show up on their online account as well as in the desktop app) but then mark some sub-folders as restricted so only certain people with the specific permissions can see/access them?
