I just bought Switch Sound File Converter and have a question that seems like it should be obvious... but I cant see the answer. I need to edit the tags for a load of files I just recorded - so I want to give them all the same album and band name. I know how to do this in Windows Media player -just select them all edit the tag and the album/artist tags are added for all selected files. Tried this in Switch and it changes only the first one of the group. Clearly this can't be right - anyone know the trick to get them all updated? I saw someone else ask a similar question here a few months ago, but he'd had no replies so I thought I'd check again. Thank you, Jim Pollard
