Owner and Permissions
Change Owner and Permissions
To change permissions not by mistake you first have to click onto the lock buttom. Then you can change quickly the wanted permissions with a few clicks onto the popup menus.
If you are not the owner of the file you first have to authorize yourself.
Templates of permissions
If you use some configurations quite often (e.g. like "I want all permissions") you can save it as template. Then you can use it with one click from the popup menu. You can decide for every part of the configuration, whether the existing permission is changed or not: Every specification in the template will overwrite the old one, empty fields will leave the existing permissions untouched.
Your actual permissions are signalized by the permission-button, too. Read on this:
