Under NT/2K/XP, at least, you should be able to use CreateFile() to open the
drive directly and then use GetFileTime() or GetFileInformationByHandle().
Under Win9x/Me, you can't open a rive directly, but instead query it
indirectly using VMM32.VXD.

You can use SHGetSpecialFolderLocation() and SHGetPathFromIDList() to
resolve a "special" folder name into its physical user-specific location,
and then use FindFirstFile() with that path instead.

According to MSDN:

    ftLastWriteTime
    A FILETIME structure. For a file, the structure specifies when the file
was last written to. For a directory, the structure specifies when the
directory was created. If the underlying file system does not support last
write time, this member is zero.
