Answer 2

Answer:

If you've ever downloaded something from the Internet (which is pretty likely given the fact that it's 2017), there's a good chance you've come across ZIP files, (or some other type of file compression like RAR or 7Z).

There's also a good chance you're not entirely sure how file compression works, which would explain why you're reading this post.

Out of the hundreds of different types of file extensions, compression files like ZIP are unique. They aren't designated to images, video, audio, or any one type of data.

Instead, they are the result of compressing large files into something more manageable. By compressing a file, data takes up less space, and files can be sent and received a lot more quickly.

But wait, how can you reduce the size of a file without ruining the data? It might sound impossible, but once you know what's going on behind the scenes, it makes a lot of sense.

So if you have ever wondered "what does compressing a file do?" then you are in the right place. So, let's get started with some of the basics.



What is file compression?

It's true that ZIP isn't the only type of compressed file, but it's definitely one of the most common. We could go on and on about ZIP, ARC, ARJ, RAR, CAB, and the dozens of others, but they all essentially function the same way. So, for the purpose of keeping this post clear and easy to follow, we'll be focusing on just the ZIP extension.

Essentially, a compressed file is a sort of archive that contains one or more files that have been reduced in size. Since these file are smaller, they can be stored without taking up much space, or transferred at higher speeds over the Internet. By using a program such as WinZip, you can then decompress the file or files back into their original state without any degradation.
