Folder Settings Explanations Needed

Can you please explain to me the differences of the folder permissions
Read only from what I understand can download a preview and any renditions and that is it.
Read/Write can delete photos, can create subfolders, and ??? but can’t ???
All Access can delete photos, create folders, and ??? but can’t ???

Thank you for clarification

All Access can do everything in a folder, including folder settings
Read/Write can read and write files, but cannot delete them or access
