OK - this is to funny! I just noticed that same file today, I had never noticed it before!? Then after reading the linked article I know why - I loaded a few new actions into my PS4 software, and in doing so had to click on "show all hidden files" - which this one usually is! Well, now that I know I can turn it off, I think I will!! Certainly can use less clutter on my computer anyway!!! Thanks for all the info!
Blessings,
