I've always been surprised by the number of icons that Windows has in
imageres.dll. I noticed that there is a blue folder (shown) and that I had never seen it before under Windows.
With my research, I found only questions about the folder compression icon (the arrows – thank you, Google). I am absolutely sure that there is a significant use for them.
Has any one ever used them? I only used them manually to bring out some files. Does Microsoft have something to say for them?
