How can I see music file formats in I-tunes 12.6?
Some of the music files in my iTunes library imported from CD's are in m4a format but older imports are in mp3.
How can you see whether music files already in the library are in mp3 or m4a (or other) formats within I-tunes 12.6? Is using the finder really the only way to see what type of extension a music file has in an iTunes library?
If the answer to the latter question is yes, is the best way to delete unwanted mp3 files with a view to reimporting from original CDs (if available) simply to trash mp3 files from the iTunes Music folder using the finder rather than deleting files (having first checked they are mp3 format with the finder) from within iTunes?
