    Tested in LTCB. http://mattmahoney.net/dc/text.html#2024

    v1.1.2 GUI has the same problem as v1.1.0 so I ran flashzip.exe directly. (I prefer command line anyway). Compression is worse (but faster) I guess because the high compression options -mx4...-mx7 were removed.

    Nania, can you please add support again for these high-compression modes (like -mx4..-mx7) ?

    Thanks !!

    Let's see what I can do in future versions to extend the options.
    What interests me and who express an opinion (even negative) about the program and what to improve, thanks.

    Why Flashzip 1.1.X doesn't compress TIF images with internal image codec? 1.0.0 compresses TIF very fast and very good. BMP is ok in 1.1.X (image codec)

    I was able to verify that an archive created with a corei7 decompresses not correctly on a pentium 4. This is due to the fact that Flashzip creates a table (array) through a void that evidently is not a standard for all CPUs. The next version will get one or more tables set out to fix this problem and make an archive that is compatible across all x 86 cpu at least last generation.

    Unfortunately for various personal reasons I can't devote a lot of time.
    I retested on various types of x86 CPU one "Flashzip archive" and were fully compatible and functioning.
    I think in the previous test has used a previous version of the file which was not compatible.

    Then you can easily compress your data with Flashzip!

    Thanks. I added it to the 10GB benchmark. Is that a 2.66 GHz processor? How much memory? What OS?

    Tested flashzip 1.1.3 on the 10GB benchmark on system 4 (Linux under wine). http://mattmahoney.net/dc/10gb.html
    With options -r -mx0 -k7 -b1024 -s the size is larger than you got, 3901 MB instead of 3872 MB. Decompression verified except file dates and empty directories are not restored. I also tried -t3 with these options since the test machine has 2+2 hyperthreads and there is one other process that I guess controls 3 separate compression processes. For awhile all 4 ran at close to 100% CPU each (according to top) and produced 3 output archives about 1.25-1.28 GB each with extensions .flashzip, .flashzip2, .flashzip3. Then it said "close task's active" and 1 process continued to run at 100% CPU for 3 hours until I killed it. This was under wine but I saw this behavior once before in real Windows (32 bit Vista). Usually it works.

  17. Thanks:

    Awaiting release in full package for installation, release version 1.2.0 compatible with version 1.1.3 and just replace the folder WFlashzip.
    This version fixes a serious bug in file type recognition.

    I wanted to know how can I solve the problem of filenames Chinese, Japanese etc.
    There is a library to invoke, or a specific API?

    See zpaq source for handling international characters in file names.

    Code:
    #define UNICODE
    #include <windows.h>
    makes all Windows command take std::wstring, L"filename", array of wchar_t, etc. In zpaq, I convert UTF-16 to UTF-8 to store in the archive and convert back for I/O. Linux uses UTF-8 natively. Look at class File, function printUTF8(), wtou(), utow() (my UTF 8/16 conversion functions), main() (for command line args). In general look at all "#ifdef unix - #else - #endif" to see how I make zpaq portable between Linux and Windows.
