'How to compare two files and delete the difference

I have two Linux directories which are essentially backups and are kind of duplicates with minor changes, I want to compare two the files and delete the difference.

For example: I have two directories.

/root/backup/2022-04-15/CS2-VM (contents:file1.txt)
/root/backup/2022-04-16/CS2-VM (contents:file1.txt , file2.txt)

I want a way to delete file1.txt because they are duplicates, how can this be done in Linux?

bash
