It backups pilot files - PilotxxLog.txt, PilotxxDossier.txt, PilotxxSquads.txt and PilotxxClaims.txt, which is enough to allow user fully resurrect his fallen pilot. It backups only one pilot at once - WOFF's currently active pilot.
Ah, I see. It is not a replacement for mine then, but a good recovery feature for your program. If a user uses my program to backup WOFF pilots and other files there is an option to start the WOFF sim right after the backup is complete. Without your backup feature, running my program will also restore the pilot to it's status just prior to the failure.
That's good that you explainex it. Thanks
