Forum Question: Workflow to rename multiple file extensions?

I’ve seen and used workflows to batch rename files. But how do I batch rename the extensions? I’ve a bunch of m4v files that I want to rename mp4.

    An extension is just part of the file name. If you have a way to rename a bunch of files, you can use the same technique to change their extensions. What batch rename process have you used?

    I loaded a USB music stick from itunes with songs that have .m4a file extensions. My 2010 Chevy truck can’t read these files. The operator’s manual says I must use either mp3 or wma. I opened the music stick files and changed 4 songs to .wma and tried it in my truck, it now shows up on the display in the truck but says it is an unsupported fie and still will not play. Any suggestions?

      Did you convert the files, or just rename them? You can’t just rename the files, that won’t work. You have to change the data in the files so your car can understand them. You can convert the .m4a songs to .mp3 using iTunes. See http://macmost.com/forum-how-to-convert-to-mp3-in-itunes9.html

        Yes I see where I went wrong. I just renamed them which I was suspicious I had done. Thanks Gary
