Content Objects, often referred to simply as "Objects", are the different forms of content that can be added to folders in your workspaces.
Objects include external files such as MS Office, PDF and other application files or Collanos Business Objects, such as Notes, Discussions, Tasks and Links.
These two different object types differ in the various tasks that you can perform with them. For example, you can rename a Note but not an external file.
