I hate duplicate music files when using UPnP. It happens because I bought some music in iTunes as
.m4a and need to convert it to
.mp3 to use it on different players. So a cleanup of my library was neccessary, but how to do it?
- Identify m4a files.
- Convert it to mp3 (with iTunes).
- Move m4a to another location outside iTunes library .
- Remove invalid references in iTunes (because of the move).
Here is how to do on a Win 7 machine:
- Use terminal to list files in a text file:
1.2 Navigate to your music folder and then
for /r %M in (*.m4a) do @echo "%~nxM", "%~zM", "%~dpM" >> filelist.txt1
- Identify files to convert and convert it in íTunes to mp3
.m4a(terminal, first navigate to your music folder and then)
forfiles /S /M *.m4a /C "cmd /c move @file C:\TARGET"2
