The Save Project command preserves the current state of your Web app. Then, you or a colleague can restore that exact view at a later time with the Load Project command. A few examples of instances where this is useful are:
•You need to save your work at the end of the day and resume the next morning.
•You want to pass the project file to a colleague so they can see your work.
This feature is intended as a short-term storage and retrieval. As underlying map services and data change over time, this file may no longer work as expected if stored long-term.
When you save your project, everything is preserved in the project file. This includes:
•Map extent, layer state (on/off, transparency)
•All markups
•Location notes
•Measurements
•User-added data from an Esri portal
•User-uploaded data from a file
You can configure the Save Project and Load Project commands to appear anywhere in your layout as a button or menu/toolbar item.
