In the command line in Windows you can still do magical things like, say you want to convert some videos in D:\Videos\ and ffmpeg is in C:\Program Files\ffmpeg\bin . You can open the command line and enter: D: # changes to D: Drive cd Videos # enter the Videos directory cd "C:\Program Files\ffmpeg\bin" At this point the prompt will still say D:\Videos> and you can type "C:ffmpeg my-movie.avi" and Windows will execute ffmpeg from the "current directory" of the C: drive, but process the file D:\Videos\my-movie.avi .
