Hey

I have files names containing parentheses. it looks like "You Ruin the Day (bonus Track)"  
I need to know how to change these lower case words right after the parentheses to upper case automatically. It should then looke like "You Ruin the Day (Bonus Track)" ![<_<](https://community.mp3tag.de/uploads/default/original/1X/5996dbb474c88b8f9fc49f09dc3858d081055a2d.gif "<\_<")

Thanks
