The first thing you will see when you start EnSight 2025 R1 is the Welcome screen.

From the Welcome screen you can load a session file, most recently used data, view screencast tutorials, or jump to a file dialog to load new data.
A list of example session files are provided with EnSight and show up in the Welcome screen under the Sessions tab. As you select each one in the list, a preview image will appear together with a brief description. To load a session file simply select it and hit the button.
A session file is a binary file containing state information and may (optionally) contain the data. As shown below, a session file can be saved by the user by selecting the Save Session... option from the File pulldown.
Note: The version of EnSight as well as the dataset name is shown in the title bar at the top.

From the Welcome screen Data tab you are presented with a list of the most recently used datasets that you have loaded. This is functionally equivalent to accessing this list via the File → Open recent data file.
To use simply select the dataset you wish to load and hit the
