I found a good article about the disk explorer
http://www.codeproject.com/KB/vb/Disk_Size_Explorer.aspx

And it ran well on Windows XP, but the text font on the chart was ugly when
ran on Windows 7, look scratchy.
I researched the code about the font for long time, it used DrawString
method to draw the text string, but i did not how to correct it, can anyone
correct it?

Every overload of the DrawString method specifies a Font object as the
second argument. Research the Font class here:

http://msdn.microsoft.com/en-us/library/system.drawing.font.aspx

and you should be able to change the font to something that looks better.

I have changed the font to the specified Aril, regular, but the shown font
like bold and irregular, i think maybe the GDI+ caused the problem or there
are some changes from XP to Windows 7.

Maybe ClearType was turned off on the Windows XP machine and is turned
on on the Windows 7 machine. If this is the case, you'd have to adjust
the drawing code. When drawing the same string onto a certain surface
more than once, the ClearType subpixel colors add up, which leads to a
horribly looking result. You can solve this problem by redrawing the
background prior to drawing the string.

Thank you, i think you are right.
"You can solve this problem by redrawing the background prior to drawing the
string.", i do not understand your meaning, could you please tell the
details?
