DOS命令将子目录中的所有文件移动一级，而不覆盖相同的文件名，唯一大小

MY QUESTION:

I have the same situation as Rishi. I have a number of versions of the same song by the same artist that appear on different CD's. If I use the batch command as written, will DOS overwrite songs with the same name, even if the file size is different for each unique file?I have the same situation as Ris
