Any half decent duplicate file finder will ignore file names and first check the file sizes and after that the file content. For example, https://github.com/qarmin/czkawka Do notice that most people do not really understand what duplicate files mean in this context. Two files in this context are duplicate only if they are on a bit level exactly the same. Every single bit. For example, if you use a text editor and save "Hello world" text as a TXT file and a DOC file, those two files have identical content. But the files are not bit by bit duplicates. Similarly, image files that have the exact same content but different file format are not bit by bit duplicates. Some duplicate file finders will be able to detect these types of "not a bit by bit duplicate but has same content" type duplicate files as well, but this type of analysis is much more difficult and also slower.

This is built into VSCode if you already use it. In the list of open files you can right click on one and Select for Compare, then right click on the other and Compare with Selected. It then opens a diff comparison of both files with the arrows in the top right to jump between diff sections. More on reddit.com
