RE: In win32 App, NtQueryInformationFile only queried fil e name, how to get the volume name as well

No you don’t. You called NtQueryInformationFile and got the file name. Now
call GetFullPathName with the results from that call.

I have only a file handle, not file name.

From MSDN
"GetFullPathName merges the name of the current drive and directory with the specified file name to determine the full path and file name of the specified file. It also calculates the address of the file name portion of the full path and file name. This function does not verify that the resulting path and file name are valid or that they refer to an existing file on the associated volume. "

As such the results of GetFullpath doesn’t have any correlation to the volume specified when the handle was opened.
