Nope.  What you have to do is recursively go through the directory
with FindFirstFile/FindNextFile type functions and add up the file
sizes.  The other thing you have to decide is if you just want to
know the total of the file sizes, or the actual space taken away
from the file system on that drive.  IOW, there is a cluster size
used by the file system, and if you divide the file size by the
cluster size, any non-zero remainder means you have to
increment the count of the clusters used.  As example
if you have a slew of 10 byte files in a directory, they
might actually use 4KB or 8 KB or whatever, apiece 
on that file system.

Depends on exactly what you are doing if you need
to account for cluster size or not.
