When you open a file in sliceOmatic, the program create a "sliceOmatic_crash.scp" file in the user's directory. This file is kept up to date and contain script commands to re-load the files that are currently opened in the program. When you exit the program, this file is deleted. If the program crash, the file is not deleted. The next time you start sliceOmatic, the program detect the file and ask you if you want to reload the same files.
