Yes, I use Wav MP3 converter for it.

It has the handy "choose contents of the folder I say" feature. Though, the trial version only converts 30% (or was it 60%) of a file, so you must either buy a full version of it or get a full version someway other *crhm* way.

Because forum rules say no warez, I cannot help you gain this version - but it isn't quite hard to find a full version of it *crhm*.
