If InfoDrainage crashes for any reason, you may be able to recover the latest version of your work upon restarting the software.
In order to prevent data loss, the Autosave option can be set in the Preferences menu to automatically save a backup of the project, and how often it will create the recovery file.
Open the Preferences dialog box by clicking File > Preferences.
Set the Autosave frequency by entering the time in minutes.
To disable autorecovery, remove the check mark beside Autosave.
Select the file(s) to be recovered and press Recover.
Selecting Skip will ignore the recovery step.
