Why My RAR Archive Contain Same Name Files And How To Extract It?

As you can see the screenshot of a RAR archive of a game file contains the same name files that are actually a big file packed in split RAR of 4GB per size.
enter image description here
Now when I try to extract them I get the error of the same file and asks me to RENAME or OVERWRITE. I tried to RENAME and after extracting when I run the file then only 1st file run successfully rest of the files become corrupted.

Can you tell me how to extract them successfully…???
