How to merge three event log “directories”‘ entries into one single textfile?

In the past, my colleagues have created a program, which writes information to the event log: “Application and Services Logs”, “Company”, “Program”, and in there there are three event logs: “Analytic”, “Debug” and “Operational”.

I can very well understand that this separation can be useful for an experienced developer/user but for a starting developer, this is a problem.

Therefore, I’m looking for a way to merge those three event logs into one and translate it into some flat textfile (like a regular logfile), something like:

2026-09-30 15:50:00.479 | Analytic | [1792:382] | Read [0] bytes from file. dwDummy=[0]
2026-09-30 15:50:00.480 | Debug    | [1792:382] | Both nBytes and dwDummy are zero.

Does anybody know how to do this?
