    Just checked on the NanoZip site and found this link, hope it hasn't been mentioned already but a search of this site found nothing so thought i'd post it.

    The site is run by Sami Runsas himself.

    And strangely BALZ and QUAD are both tested with Normal compression mode. Note that both programs have a switch for a higher compression which still untested...

    Disqualified. Does not compress anything, no error message is given.
    Please Help me !
    I don't succeed in understanding what he/she wants to say !
    Time limit ? Crash ? or other ?

    Flashzip failed to compress the file and didn't give any message what's wrong. Most likely crash.

    Hi !

    Flashzip0.92 evidently fails the compression with determined core in how much with my Intel Core duo 2 are all right everything, while trying him/it with an AMD 24OO fails the test!
    Flashzip Crash only in AMD core's !
    Am working to the version 0.93 that still needs test and that I will release soon with good news !

    Did you use intel specific compiler switches and/or hand-written assembly?

    Hi osmanturan!

    Don't be a problem of compiler, the fact is that with the version 0.092 had introduced the wide use of multilevel Hash of bit that some problem of LZ-Match (true) has created me with the chip AMD!

    Incredible or not!

    Incredible BZP UNRATED ??????????
    BZP is archiver and single file compressor!

    IS ARCHIVER !

    Best command:
    example of compression
    BZP r c:\test\ c:\output
    example of decompression
    BZP d c:\output c:\out\
    Simple or not ?

    Is BZP a compressor from me made a will on over 20 GBs of data, has you/he/she passed all the most important tests inclusive SQUEEZECHART I don't understand in what it doesn't work?

    Hi Francesco !

    Maybe the reason for "disqualify" is the absence from msvcrt70.dll on the test system ?
    Does hook need this file ?

    "Disqualified. A messagebox appears once the program is executed 'hook.exe - Unable to locate component... msvcrt70.dll"

    Hi! Good question !

    Have need of this DLL but this doesn't mean that doesn't work! deal with a DLL free for Download! The difficult to understand is that BZP doesn't work!

    Indeed, it is.
    I used it a lot on both my AMD-based and Intel systems, with different OS systems. (WinXP SP1,2,3 Vista Prem 32b SP1 and even on W2000).
    I never got a problem with your latest version (there is only one, actually).
    Maybe ask Sam about it ?

    @PAT357

    Dear Pat357 me as have said so many so many times I don't manually make the tests but I use a program that verifies the content of the source and destination and evidently they are not equal!

    Where are you talking about ?
    I was saying it's indeed very strange that someone can't run BZP ; I tested on different hard- and software-platforms and never got I problem with BZP..

    I can't always follow you....

    I'm sorry, but I'm completely lost as to why you start criticizing on me ??

    Should I take this stuff personal ??
    Are you sure you're not confusing me with somebody else ?

    Help please !

    Cannot believe there, really, have personally tried Flashzip 0.93B on a PC equipped of processor Atholon AMD 2400 and has not given some problem with all the parameters! I would appreciate to this point a help, considered that has passed the whole other tests! Where is the error?

    Examples of compression :

    Flashzip source destination

    Examples of decompression :

    Flashzip -x source destination

    PS

    Perhaps a help can give him/it me, Sami have looked and checked that the program Flashzip.exe is cleared from Windows for the execution (has often happened Me with so many programs but I don't have them certain disqualified!!!!! all it takes is authorizing them with the right key of the mouse him it goes to the Menu)

    You could try the Pagefile training him/it
    Problems that are created disabling the Pagefile.sys:

    If you have installed XP on FAT32, you have good probabilities to find you
    corrupt file if not even to find you the damaged FAT32 and therefore to install everything making a format

    If you have the NTFS you have good probabilities that nothing doesn't happen, even if however these sudden blocks could bring in the long run however to find you some corrupt files.

    Me use commands API of "windows.h" and are they possible incompatibilities?

    New Update is Online!

    2009 August 15
    Flashzip 0.99b3 submitted by the author.

    Packet 0.91a added.

    The site has another new feature, a comparison tool. This tool helps comparing two or more compressors (or configurations). See 7-Zip vs WinRAR for example.

    Since fast compressors add no significant strain to the benchmark system, the following modification is made to the qualification rules: any compressor that is faster (either compressing or decompressing) than PPMd Jr1 (default conf.) is qualified. Squeez, JAR, bwtzip, QazaR, flzp and other compressors qualify and additional configurations from XWRT, lzturbo, Flashzip, and from several others now qualify as well.

    Sami:
    Ok. I just tried the program, but "csc3.exe -m1 -d1 test out" crashes.
    Probably the problem is with compiler switches (you need to disable SSE2
    etc).

    Compression ratings.com:
    Tests are run under Athlon XP 2200+ CPU (family 6, model 8, stepping 1) with 768 MB memory using Windows XP with pagefile disabled. The CPU supports MMX, SSE1, 3DNow!, 3DNow!+ instruction sets.
    I think it maybe explain why some programs crashed as some posts mentioned.
    Fortunately, Sami compiled a new one on my source and tested it.

    New Update is Online! by Sami Runsas!

    2009 August 27
    Flashzip 0.99b4 submitted by the author.

    The site has a new feature. Top 10 page shows a brief summary of the results for the best compressors by rating.

    The qualification threshold is reduced again, to a 1/10 rating of the best one (previously 1/6).

    2009 September 30
    Flashzip 0.99b5 submitted by the author.

    Fixed an error in Application1 timings for Flashzip 0.99b4 -m1 -c7 -b8.

    Changes to the corpus. Audio1 set is replaced by a 'mini' version that consists of the same samples cut in half of the original length. Now the audio has a weight of 3% and images 3% in the corpus. Text is overweighted at 9% (on the other hand text is more compressible than audio or images) considering it is unorthodox to find hundreds of megabytes of text in one place
    Flashzip 0.99b5 gain 4^ position!

    Reference files is a new feature for the site. We run tests with common test files with all compressors (including those that did not qualify for the main benchmark).

    If I didn't miss something, there isn't comment about how many cores does compressors used in each test cases. I think it is technical important.

    PS: Thanks for the new tests, very cool!

    I agree with Fu.

    I believe Sami has also proposed a separate one-core ranking ?
    This would help to compare pure algorithm efficiency, as opposed to multi-core distribution efficiency (which is usefull too). Currently we are lacking this visibility.

    As a second note, I'm surprised by one of the changes :

    Application2
    MinGW compiler with files copied into a single file in random order.
    mirror: http://compressionratings.com/files/cr_app2.tar.7z
    Why random ? And not the usual TAR ?
