    Support for mobile devices and android?
    Chris Steinbeck BellC Chris Steinbeck Bell
    Hello. I would like to know if there is some way to open .pa files on mobile devices such as the ones using android. I wanted to use it on my samsung phone but i could not find an app or something that would let me to open those files. Do somebody knows how to open them or could it be that there is a powerarchiver ver for mobile?. Thanks in advance.

    Make .PA open to others programs?
    A Anaru Sensei
    Good morning, I bought Powerarchiver Toolbox because I find the .pa format brilliant! The problem with this format is that only Powerarchiver can open it, so it won’t be as famous as the .rar or .7z! In my opinion it is okay to have the exclusive of the creation of the format, but not of the extraction, otherwise it will never be used by anyone because few people have Powerarchiver! I hope that one day the other extractors will be able to extract the .pa format, I will be able to create archives and send them to whoever I want!

    PowerArchiver 2019 Toolbox International with Advanced Codec Pack
    F farkpoint
    Hi, I have such a problem. 03.09.2020 I bought this program, I received the registration data that I entered into the application (copy and paste), the application restarted and again reported that it is not registered. I tried it several times, online and offline, I logged in to the web account, I sent the activation email again, I entered its data, but I still can’t register it. So I wrote to support and on September 3, 2020, three hours later, they sent me a screenshot that they managed to activate the program. I thought I might have something to do with windows, so I reinstalled. But that didn’t solve the problem. It cannot be activated in either version 19.00.59 or version 20.00.53. When I wrote them that I still can’t do it, I even sent it to them both in screenshots and in the video, even after reinstallation, and I even attached a dxdiag file to them, so they don’t even answer me anymore and I don’t know what to do with it :-( It’s been a week since it was shipped. Any suggestions please? Thanks.

    Some test results of mp3 to .pa .pa experimental
    pirrbeP pirrbe
    [image: 1499762499636-9e61800d-3955-4326-b60c-ac07858f7139-image.png] ° at job status 100% the .zip closed almost instantly, pa needs a lot of extra time to finish the job… ° in speed, the classic zip is still the best choice ° PA experimental is incredible in compression but it is in the actual stage a time consumer… ° other users reported this too : PA interfaces are slower to open now. In explorer shell it takes time too, before the ‘settings’ window opens ?

    Experimental Codecs - info, updates
    spwolfS spwolf
    This is a thread about Experimental Codecs used with PowerArchiver when Experimental Codecs check is used. Currently used Experimental Codecs (from PA 17.00.81) : mp3det filter + Packmp3b codec = mp3 codec, currently around 2.5% better compression than WinZip ZIPX and 3x faster speed on 8t cpus. *** Please note, experimental codecs are for testing purposes only and will be used only when experimental checkbox is checked. Quite likely there will be no backwards compatibility with finished versions of codecs, so please use it only for testing.

    Releasing unpacking library
    J joakim_46
    Do you plan to release unpacking library, so 3rd party software can extract PA format as well? It would be great and certainly would expand the format.

    Optimized Strong, initial tests speed/compression
    spwolfS spwolf
    Hello @Alpha-Tester . Lets test a bit Optimized Strong methods and see what works and what can be improved. Relationship between codec and filter paramters as well as number of threads is complicated ones, and while we have tried to automate it in the best possible way, improvements are still possible. @skypx has a nice cpu for testing 16t performance for instance. It would be interesting to see whats maximized performance for Optimized Strong Maximum and Ultra options because they use different entropy models (a0 lzma, a1 or lzmarec) which provide different performance - lzmarec is much stronger but also slower to extract where our parallel decode helps. Debug mode can help to log all of this.

    Filters: Reflate - (pdf/docx recompression)
    spwolfS spwolf
    Filter: Reflate What is it? Reflate is advanced deflate recompression filter designed to improve compression of files with deflate streams. Obvious examples are pdf, docx, xlsx, swf, png but deflate streams can be found in many other files, usually in form of png images. Where to use it? Optimized Strong mode - PowerArchiver will compress all pdf, docx/xslx, pngs, swf, etc, files with Reflate filter automatically. PLZMA4 codec - You can enable reflate filter. Advantages Much better compression of PDF. DOCX and other files with deflate streams. Between 30%-50% on average (vs 5% for regular archivers). PDFs that are mostly big pictures wont be compressed well (especially if it is jpegs), but it will still be substantially better than regular codecs. Disadvantage: Slower speed. Examples: FY17_Proposed_Budget_Vol_1.pdf (Austin Texas Budget 2016/2017) - 20,157 kb PowerArchiver (Extreme): 9,994 kb WinRar (best): 18,356 kb 7zip (Ultra) : 18,336 kb WinZip (Zipx/Lzma) : 18,411 kb oig-work-plan-2016.pdf (Office of Inspector General plan 2016) - 4,165 kb PowerArchiver (Extreme): 1,346 kb WinRar (best): 3,790 kb 7zip (Ultra) : 3,791 kb WinZip (Zipx/Lzma) : 3,784 kb Analysis: Good case scenario. Images are likely pngs, and a lot of text that can be compressed great.

    FMA-REP - info and test results (.pa)
    spwolfS spwolf
    (This article is work in progress) What is fma-rep? Deduplication filter based on anchor hashing. Technically LZ77, but has no entropy coding, and only longer matches have a chance to be replaced with a reference. It has much lower memory requirements than lzma, so can be used to compensate lzma’s smaller window/dictionary size. Examples: Official ISOs from Microsoft for Windows 10 Pro and Office 2016: Due to large file sizes, and the fact that fma-rep takes a lot less memory than plzma4, it is very useful for large software installation DVDs that have a lot of compressed data already. Best idea is to use large window of fma-rep1 and fast codec, to achieve good compression and yet very fast speed.

      @spwolf I will look for a 320Kpbs test set. It is strange, but most of my download music, is VBR, and not CBR.

      any kind of samples will be interesting for sure…
