Documents within a project may be grouped together into a named document set. This allows the easy management of the group of documents. For example, the project navigator allows you to easily list the contents of a document set and to check out the group of documents in one operation.
Document sets may consist of documents that are related to each other based on the data that they contain. For example, in word processing documents, they may be a group of master and sub-documents. In the case of graphics documents, they may be a graphics model together with supporting database and surface parameter files.
