Hello!
I used create folder dialog to create multiple foders (so I hoped), but it didn't work; I entered
2006.08.16,2006.08.17,2006.08.18,2006.08.20
and got single folder named
"2006.08.16,2006.08.17,2006.08.18,2006.08.20"
What am I doing wrong?

I just copied and pasted your desired folder names into the Opus new folder dialog box and it created the 4 new folders just as you wanted them created.
Did you remember to check the "Create Multiple Folders" checkbox?
Well, I am sure I did.
But now it's works OK
