    Hello everyone,

    thank you
    But I get the message "File does not exist" while trying to download it.

    Edit: Now I get "Network-Timeout. www.winturtle.netsons.org takes too long to respond."

    Best regards!

    Errr... I could swear when I was at work (yesterday) there had been links to the new version "0.1" Now they are gone And even stranger: no entry "Last edited" inside the posting of Francesco...
    Am I going mad or have I taken the wrong medicine...?!
    Thanks again to LovePimple!

    i have done some tests with your new bzp archiver
    it is fast and have a good compression ratio

    but will it be possible to implement the algorithms
    from your rings 1.3 or later

    within the bzp archiver ?

    because in several cases

    rings is faster by better compression ratio

    HI!

    I am at work to always improve my programs! BZP founds him on an algorithm simple lzp but that exploits at the most the context of compression!

    I added BZP 0.2 to http://www.metacompressor.com/uploads.aspx

    I also added a new test file14 with 250 HTML pages and 250 text headers, because this file is only 5,629,573 bytes I added 3 extra digits (milliseconds) to the compression and decompression time in case time is < 60 seconds.

    Archivers can still be uploaded for live testing:

    @Sportman:
    Thanks. I've just created my profile. I advice create a new thread about metacompressor.com like: "MetaCompressor.com Benchmarks". Else, we cannot easily track your news. Best Regards.

    I finally got around to testing bzp.
    http://cs.fit.edu/~mmahoney/compression/text.html#2839
    It is on the Pareto frontier for compression speed but I have not updated the graphs yet.

    Also I noticed in testing that if I compress a file in another folder like below then the path name is stored wrong. I compress \res\enwik8 and the name is stored as s\enwik8 with the first 3 characters cut off. Then when I decompress to . it creates a new subdirectory .s and saves .s\enwik8

    Code:
    C:\tmp>timer bzp c \res\enwik8 x8

    User Time    =    12.093 = 00:00:12.093 =  91%
    Process Time =    12.390 = 00:00:12.390 =  93%
    Global Time  =    13.219 = 00:00:13.219 = 100%
    
    C:\tmp>bzp l x8

    Archive list:
    s\enwik8 size=100000000
    Total n. 1 Files
    There was no problem for the actual test where I compressed enwik8/9 in the current directory (to get proper file size).

    Also, this is actually bzp 0.2 (according to readme.txt) although program says 0.1.
