Apologies if some of this is basic

I've been using an older version of the format converter and CD ripper for a long time and have always found them excellent. However, I need to convert a load of .wma files to flac, as my music server player won't handle .wma above 192kbps, but can handle lossless FLAC.

So I purchased the full R14 Converter, but can't see how the Batch converter works.

I open a folder (either from the file list with a right click, or with Batch Converter itself), but can see nowhere to specify output folders or output format.

There must be something simple missing (and not just part of my brain)
