In case youre wondering the zip file thing is probably done like this:   
There is a thing called hexadecimal file compression. If you had a string of numbers that make up, say a picture, it would look something like this:    
1888442736abbb993dddddddddddd83666199999999477777346253   
Now instead of using individual numbers for every bit, you group them instead, and put the number of the same number before it, so if you had six 3s in a row, you'd put 63, instead of 333333.   
That number above would be shortened to:   
113824121713161a3b2913bd18133611891457131416121513   
   
The zip file thats 4.2 petabytes unzipped, probably has the exact same hexadecimal number repeated trillions and trillions of times, but could be compressed down to basically nothing.

so what happens to your computer when it is decompressed? will it just say the file is to big? or does it kill your computer? can it be fixed?

No no no,
The file contains 16 zipped files, which again contains 16 zipped files, which again contains 16 zipped files, which again contains 16 zipped, which again contains 16 zipped files, which contain 1 file, with the size of 4.3GB.

So, if you extract all files, you will most likely run out of space :-)
