The JOURNAL file format consists of update logs and scheduling data created by the InstallShield Update Service, developed by Flexera Software. These files are generated automatically during software installations to track application states, manage version histories, and facilitate background updates for installed programs. While generally safe and strictly for internal system use, these binary logs are proprietary and cannot be manually edited or opened with standard text editors.
