I just wanna try it again here, maybe somebody will shop up who knows 
where is the problem as I unfortunately couldn't fix it with degski (but 
still, thank you for your time :)). His example (can be found below) 
doesn't work on my system. The problem is I can't start iteration from 
the drive root (for example E:\), because it will iterate only the 
directory above (E:\projects\boost\build) the directory that the 
executable is located in (the executable is located in 
E:\projects\boost\build\Debug). What is weird that if I move the 
executable to the different directory (let's say 
C:\Users\USER_NAME\Downloads) it will still iterate only the build 
directory. I tried to play with Visual Studio -> PROJECT_NAME -> 
Properties -> Debugging -> Working Directory, but without a success. 
According to degski he has the value of this entry set to $(ProjectDir) 
which is the same value as mine. Thank you.
