Session files record the list of data layers open at the time the session was saved. The Session file also records the layer properties, drawing order, the on and off state of layers, and the last geographic extent of the data.
Session files enable you to re-open all data that was being processed the last time the project was open. The data types that are recorded in the session file include:
• lines
• background data
• surfaces
• last geographic view extent of the Display window
All session files have an .hsf file extension and are stored by default in …\Hips\Session. The previous format of the session file (.ses) can be opened and automatically upgraded to the new session file format.
