Regular expression check for duplicates in filenames

It can be seen that the video has a unique identifier. To check the duplicates through this identifier, the video content is the same, but the size is inconsistent, so I want to remove the relatively small files. I am not good at programming, so I asked if there is any ready-made one in the market. Software can achieve such a function? It is best to have Chinese, because my English foundation is not good, even if you don't know whether there is Chinese, you can leave your help
