There is no one single way to extract a file in any operating system, they all have a different executable platform, thus, an executable will only work on one operating system.
Most common operating systems will open .ZIP files. Windows ME and up in Windows open ZIP fine without needing to install extra software, Mac OS 8.6 and Up have the same story (You need to find Alladin, a program that manages ZIP files) and most newer Linux distributions support ZIP as well.
Also, I presume you accidentally added a poll, being both questions were the same, so I removed it
