    ... so I think it should get a real place to live in.
    There are at least two different pages to get access to archives containing it with different versions (in .zip, .rar and .7z) and partly not compatible with each other
    Bulat: would you mind to make clear which one is the right one and maybe link the older pages to point to the newest?

    Thank you!

    only 2 pages? i think it's not enough to really really obfuscate users

    btw, a few weeks ago i found web page that was not updated more than 10 years! it's a bit more that my whole web experience

    and it was page of UC2 compressor. what happens with Nico de Vries, anyone know?

    ps: i will update old page. thank you

    Thats what I mean. But Bulat updated the coresponding arc.ini. afair he gave a link to it and that was a 7z-file
    Ha! I found it: http://www.haskell.org/bz/FreeArc-win32.7z was given by Bulat in http://www.encode.ru/forums/index.ph...page=0#msg3056

    But it isnt linked anymore, is it? I mean by looking at http://www.haskell.org/bz/

    Best regards!

    Although arc.ini is different, there is no mention of an "updated" arc.ini file anywhere in that thread. Also, the date of ARC.exe is older than the zipped ARC.exe.

    The following has been added to the updated arc.ini file:

    #x$rgb = mmfast
    #x$audio = mmfast
    1$rgb = 1x
    1$audio = 1x
    2$rgb = mmfast
    2$audio = mmfast

    3$audio = mmfast
    #$rgb = mm
    #$audio = mm

    arc 0.36 was released feb 22

    in march i was updated this version changing only arc.ini file. the new settings should help to better compress MM files (using grzip instead of lzma), but now i can say that sometimes this helps, sometimes doesn't

    about arc.exe dates - afaik, both are "1,674,240│22.02.07", the small difference may be due to daylight time offset, which is handled differently in zip and 7z archives

    overall, both version are equivalent except for arc.ini change. in future, i will make both 7z and zip distros with the same contents

    Thank you very much, honestly!
    Its kind of confusing, when I (anyone) point someone else to your site, he downloads the zip-file and gets different results than me with the 7z-file.
    On the other hand: if "different" versions co-exist, they could do so, but are better named different to better distinguish them.

    Best regards!

    No, this is incorrect.

    Arc.exe from the 7-Zip archive: 21 Feb 2007, 23:19:20

    Arc.exe from the ZIP archive: 22 Feb 2007, 01:19:20

    Probably the one with external MM compression!

    this depends on where you live. seems that zip format saves local time while 7z keeps GMT one

    Seems true. My time is GMT+1. Zip shows 1:19, while 7z shows 0:19

    Sorry for delay, but my wife has caught an illness, so besides my "normal" real life, Ive got to (and want to!!!) deal with her to get her back in place! Priority -> non_plus_ultra!
    Now I am at work, so please be patient, I will check when I come home (this evening, or at least Thursday = tomorrow)
    Promised!

    Best regards!

    Although I consider my computer to be just as much a part of my "real life" as my wife, or any member of my family, I do agree that your wife (or anyone else for that matter) has a *MUCH* higher priority than the computer.

    Yes Sir, but that does not necassarily mean that I can ignore your question. I wanted to make clear that I noticed your question and deal with the answer when I have time. Because you are a real person too. So I have to show you my respect, and Im happy to see you waiting polite and understand me. Thank you!

    Best regards!

    Just got around to testing it.
    http://cs.fit.edu/~mmahoney/compression/text.html

    It is a LZ77-Huffman coder. In max compression mode it is right between tornado and thor with much less memory (3.5 MB) but a little slower. But I found the self extracting archive feature failed on enwik9, chopping off the last 21 bytes. Too bad because the self extracting programs are smaller even with the attached decompressor. Normal decompression worked OK.

    i tried few times to works with freearc, but i dont' know where to get the switches i have a .doc with a lot of "????" but helps nothig i read the "help" of the arc.exe and i see:

    "-mMETHOD --method=METHOD" wich method?
    how many methods i have? witch switches can i use? how works the .ini?

    I really miss examples and a "real" explanation how it works and how to use, looks a ffmpeg project, works great but the documentation it's 0

    Thanks!

    i'm sorry but docs are still in russian and unfinished. it's why i never advertized it in english forums.

    nevertheless many freearc options are just copied from rar. you may look its docs (rar.txt, because rar.hlp doesn't document all options).

    -m switch has -m1..-m7 variants. -m7 requires 1gb of memory for both compression and decompression and slowest but provides best compression. -m6 requires 512mb and so on...

    btw, you can use --display option to see mem reqs when performing compression
    there are also -m1x..-m8x switches that use the same amount of memory for compression but much less for decompression. also decompression is faster, but compression is slower and worser compared to corresponding -mN methods
