- fstream.hpp: Implementation of function narrow_path(const std::wstring & file_ph, ...) This function doesn't work at all on my system, it returns always the empty string. Why is this 8.3 conversion needed, can this work on NTFS reliable?

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

Now I remember it: In fact I have turned off the 8.3 aliases for my machine months ago. I have set the registry value NtfsDisable8Dot3NameCreation (HKLM\System\CurrentControlSet\Control\FileSystem) to 1. Jan
