I saw a super Compressed file. It is 11MB but After extracting it is 2.5GB according to the Poster.

Here is the link

My Problem is how to make Files like this? I saw some files in Games like this.

Thanks

Compression involves recognizing repeated patterns and storing them in a non-redundant way in order to reduce the file size. There are few basic compression algorithms to do them. Ziv-Lempel is one of them I was taught at my IT courses.

I am attaching a file that I just created. it is almost 4GB, but when compressed it is just about 1.8MB . File contains a repeated single character. File size is high since it is containing RAR dictionaries etc. (Can't zip this file, it is too large)

Those ripped games use very high compressions. And decoding them is going to be extremely resource consuming.
And I have no idea how the OS image in your given link is compressed so much. Although I *irated this copy of windows, I got it from a place I trust.

Thanks For the Reply Buddy
