When you add a document you will choose a virtual folder in which to store the document. The folders represent a hierarchical view similar to folders on your computer. The folders make it easier to organize your documents and find them quickly.
Organize your documents by assigning them to a folder and match the folder structure to what you are currently using.
Site administrators can set a "default" folder that will be pre-selected every time a user adds a new document. The user can over-ride this folder selection.
