Ok. The response on your volume change is a consistent 2.2 sec. Nothing to worry about (for this SFS).
But you may have a look at this file : C:\Users\BD\Downloads\XXHighEnd-09-z4-1\XXRequestPending.dat and see what is wrong with it.
Don't bash around, but carefully look and tell me. It looks like some rights problem, but I can't be sure.
When you carefully examined it, with some beautiful attempts to tell me what's up with it (read only, whatever), try to delete it. Here too, please tell me what you run into, or what looks special to you at "just" deleting it.
Do not solve the probem and be happy *without* telling what happened, because a next time you will have it again. Guarantee.
Anyway, your problem is there somewhere.
One additional remark, and it may be totally irrelevant, superfuous and whatever, but don't use these strange places to put rather offical "software" in. It is all not made for it, which to me feels a bit similar to using Program Files, which does NOT work because of rights probems, them by itself coming from this all not being an official install. Here you use the \users\bd\ folder, which is also special because it is not you who create that, but the OS does (at creating your userid). These things
can cause anomalies beyond my (our !) understanding and knowledge, and which in the end are my fault because not using official installs (which by itself is to our benefit). Similarly I would never put (music) files to the desktop (which I see you sometimes doing) because that too is a "rights" thing. And not to forget : the desktop isn't even there - quite illegally (Unattended) and don't ask me what can happen *now*.
All not your fault (and merely mine), but why do it in the first place ? For example, I never ever put any (e.g.) Word document in any \documents\ etc. folder Windows reserved for me for just this. Rights will be different, behaviour may (look at NAS kind of stuff, then you know what I mean), and moreover it is nothing to (be able to) deal with in any official larger environment. There we have networks, we must share stuff when we like, and the very last thing which would come to my mind is putting a file on my desktop and think another will be able to read it. Now, why behave differently at home ? there is no difference once you want to access that file from another PC.
Just telling, and no big deal maybe.
