Do not unzip this - it is a huge 42 KB file !!!

This is truly a work of clever technical intelligence, You have a 42 KB zip file that expands to 45 PB ( 1 Peta bytes=10¹² bytes). Here is what the web site hosting this file says, 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 :-) Now, how on earth does that can happen, well the answer is a characteristic property of zip compression, data redundancy, actually this file has a 4.2 GB file consisting of all zeroes, this means high redundancy and so zip is able to compress it that small. Now, go ahead and unzip it!!!
