There are many ways of storing files in a document library. The most common way is by uploading the file(s) directly from an existing document library. This is done by clicking “Add document” on the document library page (see Figure 3-37).

Another method is to simply use Windows Explorer to add a document library as a network location in Windows. The benefit of using this method is that it provides you with the ability to copy files to a document library as if it is any other shared network location. When using this method, however, SharePoint’s document management features (such as version history, check-in/check-out, and content approval) are not available.
