No. 8.3 aliases are optional on NTFS and turning them off improves the 
performance of the file system, sometimes significantly.

The narrow path should probably be obtained via WideCharToMultiByte with 
CP_ACP or CP_OEMCP, depending on whether AreFileApisANSI returns true, but 
there's no guarantee that it will be useful for opening the file.
