WDsmartware building etilqs_ files in my windows temp folder - filling my drive!

I’m a little confused. It seems like a few posters are saying that these temporary files DO get erased nicely, if the WD software is “turned off”, but do NOT get erased, if the computer is shut down.

If that’s true, then it almost sounds as if the WD software isn’t doing its own graceful internal “shut off”, when it receives a notification that Windows wants to shutdown. All applications receive a notification that Windows is terminating. This is the time for applications to gracefully shut themselves down, delete files, close files, etc.
