It may happen that a project was not closed properly and you were unable to save changes you made. The reason may be e.g. a power failure or an error in the application.
The AutoRecover option allows you to instruct the program to save the project at regular, customizable intervals. This means that the changes made to the file are at least partially saved since the last save procedure, depending on how short the chosen save interval is.
When a project is opened, the Designer will detect that an AutoRecover file is available. You can then either save the recover file under a new name or ignore the file and continue.
