Novell LANalyzer capture file is a proprietary network trace format originally developed by Novell for its network monitoring and protocol analysis software. These files are used to store captured network traffic packets for offline troubleshooting, performance analysis, and security auditing within NetWare environments. As a legacy format associated with obsolete networking infrastructure, it is primarily encountered in digital forensics or when migrating data from archival storage systems.
