Ok, in the dos prompt, after reaching the wolf directory, type dir
That will list all the files and subfolders in the directory "wolf".
Check that the game itself isn't in a _sub_folder named "wolf" and check that the exe file is in there in the correct location. If there is a subdirectory with the game, just type cd "name of subdirectory, probably Wolf" and then dir again. Look for the exe file. In any case, you DON'T want to type wolf.exe, only wolf
And I see you have met our dosraider
