How can I convert a .flac file to MP3?  

Go to download.com and look for "file converter" or "format converter".

I don't think so, but I think there will always a way to do that. I can recommend a good program to you, you can convert many types of video or audio to the other format. the program name is SUPER. Just search it with google "SUPER CONVERTER" and I hope you can solve your problem

Hey yeah that can be done, actually flac files have much better quality than mp3 but since you want to convert them, let me give you an option, the following is a link to download foobar2000 it is basically a music player and can play flac files if you want to listen to them, and can also covert the same to mp3, wav, acc or any other format you want it to... just download the player and listen or convert your flac file..... have a nice day Redhornet
