lz4/lz4

Extremely Fast Compression algorithm http://www.lz4.org LZ4 - Extremely fast compression LZ4 is a lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-core CPUs. It features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems. Compression speed can be tuned dynamically, by selecting an "acceleration" factor which trades compression ratio for faster speed. On the other end, a high compression derivative, LZ4_HC, is also provided, trading CPU time for improved compression ratio.

HatchZip - Décompresser une archive énorme sur un disque plein

HatchZip extrait une archive ZIP, 7z, RAR ou tar en la coupant par la fin au fur et à mesure : un jeu de 180 Go qui en fait 200 ne demande plus 380 Go de disque. Gratuit et open source, il vérifie la place avant de toucher à quoi que ce soit, mais reste un projet très jeune.

Pointer to Array in C: Compression File Analogy

DISCLAIMER Keep in mind that this is only an analogy to help newcomer understand pointer to array in C programming language. This does not mean there&rsquo;s any sort of compression when we use pointer to array. &arr vs &arr[0] In case you didn&rsquo;t know, we can get the address of an array using the address-of operator like &array. Here&rsquo;s an example: #include <stdio.h> int main(void) { int arr[2]; printf("&arr: %p\n", &arr); // Address to _whole array_.
