Saving a Project File
You may need a break while editing a document. 

To save work in progress, you click the Save As pop-up menu.  
In the Save As dialogue box, you choose a suitable location for the file. You can then save it as a RiverDocs project file. 

Later on, you can re-open the dot riverdocs file and resume work. 
You can also transfer RiverDocs project files to someone else, which can help to streamline workflow.
