Compare songs stored in multiple folders

[ubose]

I have hundreds of music files that are named in the same pattern (by the artist and song title) and saved in several folders. Many of the songs are duplicated in multiple folders. I want to compare across the folders and retain the copy of a song that has the biggest file size, which likely indicates to have the longest track length since the bit rate is the same for all files. Next, I want to delete the remaining copies. Please help me, a brand-new user, to accomplish this.

1. Use the search method "Find duplicate files on the basis of their properties" -> "File Name" OR the search method "Find similar file names".
2. At the search result use the select command "Select all files except the largest file in each group".
