The Library lets you organize and manage your content using folders and documents similar to how Windows Explorer lets you manage and organize files on your computer. When the Developer is installed and a new content database is created, a System folder is automatically created that contains subfolders and various documents that control characteristics of the publishing styles, template text, roles, and attachment icons.
As you build new content, you will create additional folders in which to store various documents such as modules, sections, topics, web pages, packages, roles, glossaries, and so on. The folder structure you create is completely up to you; however, it is recommended that you keep your folder structure simple to avoid unnecessary navigation or confusion, especially if you are working in a multi-user environment. You will probably want to create a standard folder structure for your content before you start creating documents and avoid letting authors build complicated folder structures along the way.
A folder can be opened to view its contents, which can be additional folders or documents. These objects always appear in the right pane of the Library. You can also open any document in a folder, thereby launching the appropriate document editor. Folders and documents in the Library can also be moved, copied, and deleted, although the System folder and its documents should not be altered.
Note: One exception to altering documents and folders in the system folder is when you are creating custom styles. See Create Styles in the Customize Publishing Styles section of the Publish Content chapter of this manual for more information.
