Walk through exactly what happens, step by step, in common situations.
Example 1 β Carol shares a folder, then Mike adds a file
Carol owns a folder and invites two teammates. What happens when Mike uploads a file inside it?
1
Carol creates "Project Files"She is the owner of this folder.
2
Carol shares it with Mike and MariaBoth instantly get access to the folder and everything inside it.
3
Mike uploads "report.pdf" into the folderThe file automatically takes on the folder's settings, and Maria is automatically given access too.
Who can see Mike's file?
πAdmins β yes, they see everythingCAN SEE
πCarol (folder owner) β yes, she owns the folderCAN SEE
π¨βπΌMike (uploaded it) β yes, it's his fileCAN SEE
π¨βπΌMaria (shared member) β yes, access flowed to her automaticallyCAN SEE
π§Other team members β only if the folder is PublicDEPENDS
Example 2 β Mike makes a sub-folder "Private"
Inside Carol's shared folder, Mike creates a sub-folder and marks it Private. Does that hide it from Carol and Maria?
1
Mike creates a sub-folder inside the shared folderHe becomes the owner of this sub-folder.
2
Mike marks it "Private"He hopes to hide it from others.
So who can actually see Mike's "private" sub-folder?
πAdmins β yes (always)CAN SEE
πCarol β yes, because she owns the parent folderCAN SEE
π¨βπΌMaria β yes, she was already invited to the parent folderCAN SEE
π§Other members β no, they were never invitedHIDDEN
β οΈ The surprise: Marking something "Private" inside a shared folder does not hide it from people who already have access. It only keeps out strangers. To truly restrict it, Mike would need it in a folder that was never shared.
Example 3 β Carol makes the folder Read-Only
Carol wants people to read the files but not change anything. She marks the folder Read-Only.
1
Carol turns on Read-Only for the folderRead-only applies to the folder and everything inside it, at every level.
What can people do now?
πAdmins β full control still (can edit, delete)FULL
πCarol / item owners β can still edit their own itemsFULL
π¨βπΌShared members β can view only; no editing, deleting, or addingVIEW ONLY
π§Others β view only (and only if public)VIEW ONLY
Example 4 β Carol switches the folder from Private to Public
Carol decides the folder should be open to everyone. What happens to the people she had shared it with?
1
Carol changes the folder to "Public"It now becomes visible to the whole team automatically.
2
All existing individual share invitations are removedSince everyone can see it now, the personal "shared with" list is cleared out.
The result
πEveryone on the team can now see itOPEN
π€It no longer appears in Mike & Maria's "Shared with me" list (it's public now)CHANGED
β οΈ Heads up: Going Public erases the private share list. If Carol later switches it back to Private, she'll need to re-invite Mike and Maria.
