I'm flopping all over the keyboard but i'll do my best to say this:
Thanks a lot for your thorough tests and video presentation to boot!! You put a lot of work into that and i appreciate it. It shows me that you're taking my report seriously and are actively trying to get to the bottom of it. I seriously, honestly, appreciate it a lot. Thank you very much!
In the video i see the lag that happens when the 500 folders are created is roughly equivalent to what happens to me. It's great that you've narrowed it down even more than i could.
I didn't seem to catch the delay when deleting those 500 folders. Did you try that? That should be quite a few seconds deleting those. I think that's quite important, because that shouldn't be dealing with any notification change code or whatever it is. Though i may just be too "inebriated" on sleeping meds, i might have missed you deleting them.
Anyway, it's all good. Thanks for your effort. I hope you can narrow it down further and get some stuff fixed up. I see that you mentioned you're looking into it, so we can leave it at that.
As for Explorer.. Why do you think i use Directory Opus? Because it's bloody brilliant in comparison! Doesn't surprise me that Explorer messed it up.
And steje, thanks for the input and advice and humor. I couldn't have gotten by without them. But, for sure, you're right that, in the past few days i've been dealing with RARing and UnRARing millions upon millions of files and folders, processing them, deleting them, etc etc. It has been a daily routine for me for the past week, and is mighty frustrating.
Ok i really, really have to sleep. Good night everyone! Thanks for everything, despite my insolence!
