I just downloaded a file from a Torrent website. It was a zip file of 652MB and when I unzipped the file, it exploded to 2.3GB!
Whoaa!! How can this be done?

    You can use B1 Free Archiver (here: http://b1.org) and don't forget to choose "Ultra" compression method. It reduces files' size significantly.

    You can use winrar, winzip, 7zip and bullzip software that can compress the files

    I would like to thank everybody for their valuable inputs.
    There is no way compressing to such small size except through some tough coding in command prompt...n i don kno about it a bit :D

    Thankxx everyone :)

    7-zip and Winrar are the best compression software. Personally i used Winrar but im not sure if you can control how much you want to compress it.

    if you look this youtube, it uses KGB archiver, compress to KGB and algorithm PAQ7 (now should be higher PAQ on the interface) and compression level: Maximum, apparently he got good results, the compression can take several hours depending on the size of the original file and also the power of your pc.

    The basic principle that lossless compression algorithms work on is that any non-random file will contain duplicated information that can be condensed using statistical modeling techniques that determine the probability of a character or phrase appearing. PAQ is slowly being adopted, and a variant called PAQ8O which brings 64-bit support and major speed improvements can be found in the PeaZip program for Windows.

    What kind of file was it? Some files such as spreadsheets are mostly empty space and compress very well.

    7Zip is the best archiving tool out there. It is free too. It can compress to zip, 7z and many more formats. However, I personally got best results with "7z" format compared to rar, zip and other formats many times. So, I recommend "7z" for maximum compression.

    I suggest you use any linux based os and compress to tar.gz

    Actually it's like this
    I write
    111111111111111111111111111111111111111111111111
    But when Compressing
    1 is there 48 times.
    So simple isn't it. But there are quite a large number of algorithms lossy compression(JPEG) Lossless compression etc for images.

      Actually the best answer of this question. Others are not understanding it.

      The amount of compression that can be achieved depends on the file itself. May be the file contained data which repeated too much times which can be compressed more than data with much less repetition.

    You can use a free utility called 7zip which compresses and encrypts files using 256-bit AES cipher.
