In particular, when filing a bug report against an application suggest that the application developer obtain the free space information using GetDiskFreeSpaceEx http://msdn.microsoft.com/en-us/library/windows/desktop/aa364937%28v=vs.85%29.aspx where the input parameter, lpDirectoryName, is the directory to which the application is interested in writing. It should not be the root directory of the path. The older GetDiskFreeSpace function http://msdn.microsoft.com/en-us/library/windows/desktop/aa364935%28v=vs.85%29.aspx requires that the lpRootPathName parameter be the root of the path. GetDiskFreeSpace does not work correctly when there are Reparse Points (NTFS Junctions, NTFS Symlinks, CIFS Referrals, AFS Mount Points, AFS Symlinks, etc) and should no longer be used.
