You can also associate sample documents with maps. When you add a sample document to the workspace, and the structure is read-only, the document is automatically associated with a map instead. Just as with structures, when the document is associated with the map, it is stored in the workspace in the Sample Data folder.
When documents are associated with a map, this is indicated in the map properties. As with structures, you may select the folder that contains the sample documents for each side (input or output) of the map. If you don't select a default folder, it is assumed to be Sample Data/<map name>_<input|output>.
