我必须将一个mp3文件从其子文件夹复制到其父文件夹，然后将其重命名，例如NEW_originalfilename.mp3。每个子文件夹中都有很多mp3，但是复制哪个都不重要。可以是第一个。
例如
folder1/sub1/one.mp3
folder1/sub1/two.mp3
folder1/sub1/three.mp3
folder1/sub2/more1.mp3
folder1/sub2/more2.mp3
folder2/sub1/aaa.mp3
folder2/sub1/bbb.mp3
folder2/sub2/111.mp3
folder2/sub2/222.mp3
folder2/sub2/333.mp3
结果：
folder1/NEW_one.mp3
folder1/NEW_more1.mp3
folder2/NEW_aaa.mp3
folder1/NEW_111.mp3
有批处理Windows解决方案吗？
