SmartDraw has a cloud storage service that houses your saved files.
While you are working on a visual in SmartDraw, your visual is automatically being saved to the cloud storage service every few seconds, with the name of "Document (Number)."
To name your file simply choose Save As from the File tab.
In the dialog that pops up, you can name your document, choose a folder, or even select a different storage service like Google Drive or OneDrive.
The file is immediately saved and is now renamed. The checkmark next to the file name indicates saving has occurred.
To learn how to save your file to a third party service see: Add a Storage Provider: Box, DropBox, Google Drive, or Microsoft OneDrive.
