ETL (Event Trace Log) files store the output of instruments attached to their application, or user or kernel events during real-time. The enable the consumption of those events post- that time.
According to file.org these files "can contain information about disk access and page faults, logging high-frequency events and recording the performance of the Microsoft operating system. This information can be used to analyze and adjust voice response software applications."

[edit] Identification
After the trace log file header the names of the logger and the log file are stored as null-terminated Unicode strings.
So ETL files contain near the beginning the bytes sequence .\0e\0\t\0l\0\0\0 triggered by used file name suffix .etl.
