I've noticed many of the cs I downloads as a rar vs zip files.
Why do people like rar files better then zip when compressing and downloading there
work to a site such as this.
I found a free program that I really like that lets me download rar files, extract them and make the file as well to download to other sites.
Just wanted to know the main difference on your perspectives who actually use this file system the most.

Thanks in advance

The only difference I see is that RAR files are much more advanced.
