SiSense Prism documents (PSM files) have a similar structure to that of Microsoft Excel Workbooks. A document is made up of one or more sheets, each of which contains Widgets that visualize and format information. These documents allow you to organize, save and share your work.

When the application first opens, a blank document containing one sheet is automatically created.
- To open an existing document, navigate to the File->Open menu (or click Ctrl-O) and select the appropriate file.
- To save a document, navigate to the File->Save menu (or click Ctrl-S). The first time you save you will be asked to give the file a valid name.
- To save a document with a different name, navigate to the File-Save As menu and type in the new path and file name
The name of the document currently open is visible from the main application title:
