			== Notes ==
			Please, please, please do not CheckSpaceFree on "c:\" when you want to CheckSpaceFree on "$INSTDIR".

			You need to know the capacity of the volume that the specified directory is in. This may not be the volume at the "root of the drive" (e.g. "d:\") because of the use of mount points. If you don't know what mount points are then you should find out before writing installers that look at disk space. You might even use them yourself :-) In simple terms, a system could have a drive on which stuff is stored; Instead of being accessed as d:\, it could be accessed as c:\stuff. So, if I want to install your program into c:\stuff, you should CheckSpaceFree there and not abort because I don't have enough space on c:\.
