R30 file

I tried the search and came up with nothing so please excuse me if has been answered. I was given a DVD that has 30 RAR files, R30-R36 files and one SFV file. I know what the RAR and SFV fiels are but what are the R30 to R36 files and what do they do, Thanks

Multipart rar files are named .r01, .r02, etc. They should be automatically extracted as part of the master .rar file.

And in case you do not have a .rar in the set, then start extracting from .001.

Thank you for the response. They did extract like the RAR files
