Hi , I’m using Renamer Pro and MP3 Tag to streamline my audio Collection, and i have many different versions of songs in my collection, I want to number them in a certain order : First DSF & DFF, then Wav, Aif, MP3, M4a etc, but when i use the serialize function in Renamer Pro It gives the same number to different file types, like 1.wav, 1.mp3 etc, and I would like to rename all the DFF’s first batch, then the Wav’s etc in order. Now I have to do this manually in MP3 Tag, is there a solution to do this automatically in Renamer Pro or MP3 Tag ? Thanks for your help

Just to get this clear: the filename is no tag. The filename is a property that is a requirement by the operating system.
Mp3tag mainly takes care of the embedded tags.
Eventually, you can use tag data to rename files.
To sort by filetype, add a column to the filelist that shows the extension.
Sort by the extension.
Then try the auto-numbering wizard Ctrl-K and set it to start a new sequence on the change of extension.
