From: Odomae on 13 Dec 2009 12:55 Given a normalized name like \Device\HarddiskVolume1\Documents and Settings\My Documents\test.txt, how do I get the DOS path name like C:\Documents and Settings\My Documents\test.txt?
From: Kerem Gümrükcü on 13 Dec 2009 22:13 Hi Odomae, [QueryDosDevice Function] http://msdn.microsoft.com/en-us/library/aa365461(VS.85).aspx Thats good enough, but when you go deeper, then you are going to use these: NtOpenDirectoryObject NtQueryDirectoryObject NtOpenSymbolicLinkObject NtQuerySymbolicLinkObject NtClose Hope this helps,...

FltParseFileNameInformation will crack the normalized name to "\Device\HarddiskVolume1" and "\Documents and Settings\My Documents\test.txt". As about the drive letter - I would never use them in kernel mode at all. Convert the drive letters to kernel device names in user mode using QueryDosDevice. Also, you can try using IoVolumeDeviceToDosName - convert \Device\HarddiskVolume1 to the device object pointer and then call IoVolumeDeviceToDosName. -- Maxim S.
