ETL files are log files that contain event logs generated by Microsoft Operating System Kernel. These log files include application and system-level errors, warnings, and other events data. ETL files are helpful in analyzing and troubleshooting system level problems. Common problems recorded in ETL files include those generated by disk accesses and page faults. Microsoft provides two applications, Tracerpt and Event Viewer to read and view contents of ETL files. ETL files can be converted to other file formats such as TXT and CSV using the Tracerpt.
ETL File Format
ETL files are saved to disc in compressed binary format to reduce disk space.
