I saved a webpage in my browser as HTML. It saved not only a HTML file, but also a directory with various image files and whatnot.
So I deleted the dir, since I only wanted the HTML file.
Windows deleted the HTML file anyway.
I assumed that I had both selected, so I restored them from the trash can and very specifically selected only the HTML file. Delete. Both deleted.
I restored them once again and tried to move the dir to the trash can. The HTML file was deleted again.
Somehow, Windows (10) has "coupled" these internally somehow, refusing to let me move or delete them individually. Extremely annoying.
I ended up deleting them and then restoring only the HTML file from the trash can. It didn't restore the dir in that situation, at least. But that's a ridiculous thing to have to do.
Why does it do this in the first place? I didn't know it could do this at all.

or something similar - check the drop down menu for the file extension in the Save Dialog.
