Session files allow you to save registered tool information, file configuration information, tool map schema information for loaded map files, and displayed windows and dialog boxes that you want to restore when you reopen the Schema Editor. When you exit the Schema Editor, the software prompts you to save your session file so that you can return to your work easily. You can create, modify, and open session files in the Schema Editor using the File > Session Files commands.
When you create a session file manually in the Schema Editor or the Desktop Client creates a session file for you, the session file is saved in your My Documents folder on your computer. The file extension for session files is .SES.
