What font and size is used in Windows 7 File Explorer Tree

Question

I am having a hard time to find out which font is used by the Win 7 File Explorer in the tree view on the left hand side. Better, of course, would be if I can programmatically find out which the right font is (C#).

I searched the Windows 7 design guidelines but this particular scenario is not listed (at least I couldn't find it).

So anyone good with fonts?

Answer 1

It's Segoe UI. In the future, you can use WhatTheFont to resolve any questions you have about what font something is.

Answer 2

P/Invoke to SystemParametersInfo with SPI_GETICONTITLELOGFONT.

It depends on the language version of Windows. If you look at Robert Harvey's answer, you'll see a character that can't be displayed by Segoe UI.
