    Scifer Archiver

    A new archiver...

    Scifer is a data compression and archiving application using a new data compression logic based on UCL (Universal Common Logic).

    Main Features

    * Best compression ratio while compressing complex, non-literal and precompressed information.
    * Creates archives with internal and external headers.
    * Provides the most flexible access to archives with third party applications.
    * The algorithm is adaptable for adding any number of new techniques of compression.
    * Least memory consumption compared to any other notable compression algorithms.

    Archive Type Support : Scifer Archive [ .sen ] | Scifer Binary Archive [.ba]

    Algorithm Portability : Cross-platform | Device independent

    Operating Systems : Windows 98/ME/2000/2003/XP/Vista | Linux [ Fedora 7 compatible] | OS/2

    Support for other types of archives : not supported in BETA version

    License : Freeware

    New programs are everytime welcome. Thanks
    My first results (tested only text files yet) aren't really amazing.
    FP.LOG over 2mb.
    enwik8 over 40mb.

    But maybe the algorithm is strong on other types.

    VERY buggy indeed. Especially the GUI version, I didn't manage to make it compress me something. The CLI one did a bit better, and the end result just shocked me. It managed to perform worse than GZip by whopping 10%!!! Noone has ever done that, lol. Though I haven't tested it on, as he said, "complex, non-literal and precompressed information" -- it was just a simple, literal and decompressed Acrobat Reader 9 installation.
    Sorry for being sarcastic. As Simon Berger said, new programs are always welcome. I, for example, have never made a single archiver.

    For me the GUI is very good and is working also like I thought.
    I hoped for a much better performance as I saw it's for all platforms, with a good website and a nice looking GUI :-P

    Can't say much about the program yet, but the site is buggy for sure.
    File does not exist. Make sure you specified correct file name.

    If they are same, UCL is a compression library which provided by LZOP's author. But, it's quite old library.

    It's clear that normal mode is worser than deflate (deflate has 32k sliding window with huffman entropy coder). So, that's why it has worser compression than GZIP. Looks like the author overpays.

    Quick tests:

    DIMES, java application, a lot of precompressed information.
    ~30s, 7570879B
    Nanozip:
    0.656s, 6990581B.

    ODS, Open Office spreadsheet.
    ~3s, 263339B
    Tornado:
    0.031s, 217796B


    backup, mostly sources, some executables, some archives:
    ~53s, 14069704B. Then it hung, created archive misses one small .xml.
    4x4:
    0.547s, 13164904B

    Currently it's far from the best, but the author seems to have some original ideas, maybe he'll make it work better.

    BTW it seems to work best on precompressed data, just like the author stated.

    Don't know about program - didn't test it. But the site is insane.
    http://www.senthilkumarr.com/Features.html - this page (some text and 3 images) weights 1,7 mb.
    Most data is done by huge http://www.senthilkumarr.com/sample+normal.png - i can't understand why anyone saves screenshot in Jpeg and than converts it to PNG to place in web.
