I have a file that is damaged, therefore, it will not save during my nightly backups. The file is QASZRAIRD in library QUSRSYS. Does anyone know what this file is used for or how I can find out what this file is used for? Can I delete the file and re-create the file, or will that cause more of a headache than I want? Since this file is damaged, if I run RCLSTG and it deletes the file, what side affects may be caused?
