I downloaded MB specifically to manage songs and podcasts on MP3 players. Amazingly for me as I'm so useless with these things, I managed to download MB and also dragged one by one my music album from my NAS drive into the inbox. They are in FLAC format. I also managed to convert to MP3's which went into the MB designated file. Following conversion, I thought that then MB would read only the recently converted MP3 files but it seems to me that when I synchronise to the MP3 players, I am transferring the original FLAC files. I don't doubt I am missing something very obvious, but I can't put my finger on it. The FLAC files on the NAS drive are used for my streamer and I only need the MP3 files on my computer having the MB software. Can anyone direct me to the guide for introducing the MP3 conversions instead of the FLAC from which they came? Thanks.
