Using Amazon Music I download an album twice. It saved each file twice. One like "song.mp3" and the next as "song(1).mp3".
I wanted to delete all the files ending with "(1).mp3". The easiest way is to use the Mac terminal and a shell. Here's the steps I took:
Opened Terminal
Change to the Music directory typing: "cd Music/Amazon\ MP3
Then typed: "find . -name *\(1\)\.mp3"
If the find command listed only all the files I want to delete then I type the next line. But I must be certain because it is not reversible. Okay, are you certain?
Now delete: "find . -name *\(1\)\.mp3 --delete"
This leaves me with a problem for itunes where there a duplicates.
