The Security tab displays a folder’s current security settings. The first column lists the users and groups who have access rights; the second column lists the specific access rights assigned to those users and groups.
When created, all three folder access rights-Read, Write, Append/Execute, and Find- are set to the primary group of the user who created the folder. A folder is not visible to you unless you have Read access rights. To delete a folder, you must have all three access rights.
