Change default output directory (folder).

Okay... What makes you decide a directory inside %ProgramFiles% or %ProgramFiles(x86)% is reasonable as an output one? Those directories are for program files, period. They're not to write program's output or even setting files!

For setting files (that you're currently writing there as well) you can use a subdirectory in %LocalAppData% or %AppData%. For the output directory, why not use a subdir inside the user's Music one?

Also, how come the directory path is being written with forward slashes when in Windows default separator is backslash? I know forward slash should work as well but it'd be nice if things were consistent.
