Hi redisland, could you tell us where can’t you rename the file? On the program or on your computer? When you renamed the audio, were you playing it? If so, generally it cannot be renamed while the file is opened or played. Also, you can restart the program and your computer to see whether the file can be renamed.
If none of the solutions works, please contact us. Our support email: @apowersoft.com">firstname.lastname@example.org.
