The document library contains folders and documents. The navigation path to access the Document Library is Select Documents, then Document Library from the top menu.
By default the document library will contain Attachments, and General folders. It will also include the Recycle Bin. All other folders can be created as business needs require.
Document Library View
Users can compare the configurations of various folders by navigating to a particular folder property on one folder. Users can then select another folder and view the same properties of that folder as long as they have equal rights to that folder. Users will remain on the same property for each folder they select until they have selected a different folder properties tab.
