.rar, .7z, and .zip use different algorithms to compress the data. There may be enough information embedded in the file that even with a different file extension a program like winrar could decompress with the proper algorithm but it doesn't mean it is actually the same and someone using winzip won't be able to decompress a rar file just because you renamed it .zip.

You can customize when you install or if installed already, in the program, Options | Settings | Integration

Associate the program with whatever ya want.

No. I meant that by changing to .zip, you could open it with winzip? I am aware of Winrars options.

That's because if the downloads are huge, it can be broken into multiple parts using rars. If one file is downloaded corrupt, all that needs to be done is to download that tiny part again, instead of the whole thing.

That practice is not as common as it used to be. Back when people would download files via "newsgroups" and binaries it was the standard M.O., nowadays it's fairly uncommon.

A good torrent client doesn't need the file to be broken down like that due to the hash checks and such.

RAR files within RAR files and multiples are considered a nuisance and unnecessary.
