.ERR File Extension
File Type 1Error Log File
What is an ERR file?
An ERR file is a text file that contains error messages generated by a program. It is typically written as a program loads, executes, or closes and is often used by software developers when testing or profiling programs.
Since programs often print to standard "out" and standard "err" streams when run, a developer may choose to redirect this output to a log.out file for normal output and log.err for error output. Both files may be appended rather than overwritten between runs of the program so that the history is maintained over successive runs.
