I am fairly new to Macs. Today I downloaded XLD. I ripped a CD to FLAC and although each of the track files has an FLAC extension, the icon for the files indicates that it is an OGG file and that Audacity is the default program to open it. When I click on the file and it launches Audacity, I get an awful sound -- probably because it is trying to read the FLAC file as an Ogg Vorbis file. If I open the file with VLC, all is fine. A couple of questions. First, does anyone know why Audacity was chosen as the default program and why it sees it as an OGG file? And second, how can the default program for opening a file be changed? Thanks.
