A couple of small notes:
1. Be sure to replace "User" with your windows user name in C:\Users\User\AppData\Local\Temp\arduino_build_692458/JackAlV050.ino.elf or you might have trouble finding your file.
2. You can replace the 'C:\Users\User' part with the environment variable %USERPROFILE%.? This is particularly helpful in .bat(batch) programs.
