When on Windows, if you use boost::filesystem::canonical() to resolve a NTFS network drive mounted in a directory, the result is what I see as a useless result.  For example: C:\ntfs_mount\other\dirs\file boost::filesystem returns: C:\?VolumeXXX-XXX-XXX-XXX\ other\dirs\file This volume notation is useless as it cannot be passed to any file function.  Also, the path is divided by a space to other\dirs.  It would be better if canonical does not mess with the network drive at all and returns the directory as is, like boost::filesystem::absolute() does. -- Gonzalo Garramuño
