    • Cannot convert archive to .zip, always creates .zipx

      C

      Converting an archive to .zip (using both the “Deflate (.zip, compatible)” and “Store” compression methods) always creates a .zipx file instead.

      Using the “Store” method sometimes creates a .zip file; I have seen it happen just now, but I cannot reproduce it.

    • Self-extracting archive creation too messy!

      A

      Good morning,
      I have been using all compression programs for over 20 years, I have always found Winrar very easy to use when I create a self-extracting archive, even 7-zip is simple, “right click” and “create self-extracting archive”, because on powerarchiver it must be like this confused ?
      It doesn’t just create the archive, it opens a page where I have to select the file again, what kind of archive, which folder to create it, etc … you should learn from your competitors how to make life easier!

    • PA archiving issue with large files and shows incorrect original content's size for all types of archives.

      G

      Hi,

      So refer this screenshot:

      image_2020-12-30_115129.png

      The properties panel that you see, is what I tried to compress, using PA, with following settigs:
      Extreme Strong optimize
      https://forums.powerarchiver.com/assets/uploads/files/1609079025475-image_2020-12-27_195344.png

      The process was stuck at 0% with no progress for over 8 Hours:

      PA.png

      Then the usual, clicking will make it go not responding.

      So, I could not get the files compressed using PA.

      I tried 7zip, and it worked, so that’s 1 issue.

      PA shows incorrect original(before compression) size of total contents.

      Refer the first screenshot.
      folder’s size is shown correctly in 7ZIP
      but not in powerarc.

      this happens with every archive, whether they are compressed in PA or not, whether it has only 1 file, or multiple files inside multiple directory.

      Neither does the archive property panel shows original content’s size.

    • PA Not responding issue and Pause issue

      G

      Hi,

      So my rig is as below:
      CPU: Intel® Core™ i7-4720HQ CPU @ 2.60GHz (Turbo 3.7GHz)
      RAM: 16 Gigs DDR3
      Samsung SSD 860 EVO
      Windows 10 pro for workstations x64, freshly installed on 22nd Dec 2020, and updated.
      PA freshly downloaded on same day, so it’s 2021 x.x.62 version

      PA Stuck.png

      Issue and reproduction:
      If you start a compression, and if it’s mid way anywhere or even started, and you try to cancel it, the window will get stuck there, another click or key press will make the window not responding, then, and more will make windows to collect logs for crash, and the process will be terminated by windows

      On the other hand.

      If the process is mid way, and if you try to pause it, the compression, CPU utilization, RAM usage will stay/increase as if the compression if still going on, the whole process will take it’s course, instead of doing what we clicked on.

      So, both pause and cancel buttons are useless.

    • PowerArchiver Queue made worse

      G

      Just installed 2021 v20.00.63

      Now, when I add to queue, with or without using always use queue.

      The powerarc starter opens up in notification bar.

      and that’s it, no matter how many files I add to queue, no compression will start.

      I also cannot double click or right click the icon.

      If i end task for this, and disable queuing, compression works fine, just that I have to manually start individual tasks.

      it’s quite ironic that you guys took whole year to fix one issue, in this versions, which completely broke the queuing feature.

      Did you guys test it before releasing?

      This resulted in negative compression.

      However same file is compressed by 7zip alpha, with positive compression:

      I understand that there are different algorithms, parameters used, and totally different software with unique sets of logics programmed, but see if compression algo can be optimized for such files.

    • BUG: Dragging and dropping not working, hangs

      AluminumHaste

      Over the last few months, I’ve been trying to track down the cause of a hanging bug in PA.
      I have found a reliable test case (on my computer at least).

      I am trying to extract the folders/files from: https://github.com/codereader/DarkRadiant/releases/download/2.9.0/windeps.7z

      By selecting both folders, then dragging over to a Windows Explorer window on another HDD.
      I’m not sure what causes this but this just doesn’t do anything, progress bar appears, but nothing happens.
      PA shows about 5% CPU utilization and I’ve left this going all night and it never does anything.
      It doesn’t always happen, but this morning this is reliably failing for me.
      The folder I’m dragging to is under Git source control, but this also happens when dragging into other folders also, but not always, sometimes it works.

      If I do a regular extraction and use the dialog box to select the location to extract to, that always works.

    • UI Issue moving between different monitors

      G

      I have just installed 2021, but seems to have similar issues to 2019. If you move the app between differen monitors (with different resolutions) the app does not automatically adjust accordingly, so on one monitor I have the app is too big for the screen, whereas on another monitor it only takes up a small fraction of the screen.
      This was worse with 2019, where the fonts were totally screwed up, making the app unusable. This seems better in 2021, but still not working properly.

    • PA 20.00.63 update still install 20.00.62

      2

      Hi.

      I have noticed after updating PowerArchiver through PatchBeam to 20.00.63, after the installer finished and I recheck for updates, it still tells me that I have version 20.00.62 installed and prompts to download 20.00.63 again.

      This also happens when I install from the offline setup file powarc200063.exe ( https://powerarchiverdl.cachefly.net/2021/powarc200063.exe ). It still installs version 20.00.62 and the process goes over and over again.

      Also, in PowerArchiver About screen I see version 20.00.62 but in Programs and Features in Windows 10, version 20.00.63 is displayed as being installed.

      Can someone check and see if they experience similar behavior?

    • Bug with opening an archive while a file is being extracted from an already opened archive

      A

      When I double click on a file within an archive the file gets temporarily extracted to being opened with the external program. When I now go back to the windows explorer and want to open another archive while the file from the first archive is still being extraceted, a new window of power archiver opens and immediatly closes. It opens and closes the new window repeatedly until the extraction of the file from the first archive is completed.

      I use the option that power archiver opens a new tab when another archive is opened.

      This happend with version 20.00.60. I wanted to update it to 20.00.63 as shown in the update window but it just updates to 20.00.62. It still shows that 20.00.63 is available but never seem to update to that version. The bug still exists though.

    • PA very slow to launch (double click) html file from archive

      S

      I have some large zip files (~ 40 MB) with a lot of html files. When I double click on one of them in the archive, it takes a long time (eg 20 sec) for the file to be extracted and opened in the browser.

      I am using version 19.00.59.

      I discovered that the root cause of the problem is that all the files in the archive are extracted to the temporary dir before the selected file is launched.

      It does not appear to happen with other file types (such as pdf) nor when dragging a html file into the browser.

      I think I recall this issue being raised by someone else, but could not find it.

    • PA 2021 associate formats popup Minor bug

      F

      Hello there,

      I was installing-uninstalling and reinstalling PA 2021 due to another bug when I noticed a minor popup “bug” if it is considered a bug, regarding application association with recommended formats.

      During PA installation you get to choose those options
      Installation 1.png

      I have ticked Associate PA with recommended formats

      Installation completes and when you open PA the defult theme is Windows Ribbon.
      When I changed it to Classic Theme, PA restarts for changes to take effect and then I get the below popup (Sorry I have a greek system)
      It asks: Do you want PA to associate with recommended formats now?
      Options: Associate for all users and Never show again.
      Popup 2.png

      I could swear that once I was changing themes and icons all the time to see which one I prefered and also toggling PA.exe to run as admin and windows compatibility mode and got this popup twice or tripple times.
      Well this one does not bother me at all, I just posted it for the records if needed!

    • Inconsistency with disabled tabs and multiple instances of PA allowed

      A

      If I the Configuration > View > Standard > Disable Tabs option is checked, when double clicking inside archives on files supported by the internal viewer (PDF, JPEG etc.) they are opened in associated application rather than on a new tab in PA internal viewer, which is expected behavior.
      Next, if the Configuration > Miscellaneous > General > Reuse PA Windows is unchecked, when double clicking on archives associated with PA in Explorer they are opened in new PA instance when there is another one already running, which is expected behavior.
      But when Configuration > View > Standard > Disable Tabs option is checked AND Configuration > Miscellaneous > General > Reuse PA Windows is unchecked, when double clicking inside archives on archive files they are opened in the same instance of PA with no way to get back to the parent archive. I would expect, that when the user doesn’t want to use tabs AND want to use multiple PA instances, that in such case double clicking on archive located inside another archive, the second one would open in a new PA window.

      I have opened this thread in reference for us to try out the new .PAF format.

      Below is a link to a large PDF this is an example in size and content to what my business and my friends business would have, Partylite is an example not what i personally deal with but it contains data, loads of pictures high and low graphics.

      Here are some stats,

      The original size of PDF is 48.9MB [51,351,506Bytes]

      Compressed with the default PA Settings in the following formats;

      Link to PDF
      http://omega.livedrive.com/item/91a1987e76934c91bc66b8727147b020

      Zip - 48.4MB [50,752,392 Bytes] 1.17% Ratio
      ZipX - 45.4MB [47,648,914 Bytes] 7.21% Ratio
      7z - 44.8MB [47,063,757 Bytes] 8.35% Ratio

      So from the above 7z Shows the best possible current method to compress this large PDF. Now what can PAF do?

      Over to you Guys…

          Very similar, some of our PDF’s are PowerPoint presentations containing HD Pictures much like this. However, I can’t provide a real example for much of it as it contains confidential sales figuires and by removing those pages i am them reducing the size.

          However, this PDF i have as an example is similar in size towards my friends Marketing firm Proof’s of such they use Images and PDF’s that make up 10meg to 50 meg Documents.

          So its the same concept, the same size with the same varibles. :)

          so… how good is this PAF?

            probably 15%, but main deal here would be to also recompress images, as images are those that are 50 MB.

            but i will let you know of real result soon.

              15% is still better than any other option in PA currently.

              What would also be nice is if you can Split like a rar the PAF format into a series of extracts so to help when emailing.

                  Ok, I am very impressed… And I assume when you open it within PA and then view the PDF there is no loss of quality? is this correct?

                  I would love to get this trialed out! I will need to speak to Martin at Modern Printing designs he is over in hong kong withi is boss Cindy Cui. However, when i get a working copy of this format on his return i will install my copy of PA and ask him to try it out.

                  He uses Outlook so in theory i would need it to auto paf each email with POAP and many of those features i requesetd for POAP V3 were relating to my and other clients experiences…

                  :) theres a reason i make requets! and 9 times out of 10 they pay off!

                              right now we are still working on codecs, speed for strongest mode (in results above) should be similar to 7zip strongest mode…

                              as to the SFX, SFX is just an small app that extracts archive inside, so it is possible.

                                That’s very good news indeed. Obviously better compression is good. Nice to know, though, that compression and extraction are still speedy.

                                  it will have to be a bit slower but overall, it is still fast.
                                  Extra compression is not due to utilizing slower compression methods (which exist and can be used, but are considerably slower to extract, up to 10x), but by doing better work on preparing data to be compressed.

                                  In this case, this is actually recompression of deflate codec, which is used to make PDF, PNG, DOCX, OODT files smaller. However, just like in zip, it is inferior compression codec and since it is compression codec after-all, you cant significantly compress it further. So what we had to do is create re-def codec that opens up this data so it can be compressed better.

                                  Hard part is to put it back together lossless, and still maintain good compression ratio, and make it all fast and seamless experience to the end user.

                                    ok, so no tasty PDFs to test? C’mn guys… we have just finished with the sample that Richard sent over. We need more.

                                    There is nothing magical here, just a LOT of work.

                                    Once again, how everything works is that we recompress deflate codec, used in png, pdf, zip, docx, oodt, etc.

                                    So (simplified):
                                    1. Extract deflate tokens from file
                                    2. Compress them with better method (plzma currently)
                                    3. Store differences between our deflate implementation and original file so we can have 100% match.
                                    4. done.

                                    Basically main “problem” here is that everyone uses different deflate implementation. You know that if you ever zipped something with PA, WZ, WR, 7z and any other tool, you will never end up with same file sizes.

                                    This is the problem during “reflate” because you cant arrive at 100% same file, you have to use differentials, just like what patchbeam uses for instance to sees the difference between new and old file.

                                    So we need more interesting examples so we can tune our detection models so there will be minimal amount of diffs, and file size will be as small as possible… Lots of diffs and then we gain no compression.

                                    For instance, PartyLite.pdf that SirRichard sent:
                                    Original: 51 MB
                                    PLZMA: 46 MB
                                    Ver1 of reflate: 44 MB
                                    Perfect reflate: 38 MB

                                    So our first versions of reflate had 6 MB of differentials needed to re-created PDF perfectly… We improved that so it ended being 100kb or so and now we do 38 MB on that file.

                                    That is before pjpeg (another codec) that recompresses the jpegs inside that PDF, so it ends up being the great 33 MB.

                                      I have been asking, unfortunetly when it comes to work we dont have daft Large PDF’s that would benefit from Compression.

                                      My Photo person doesnt use PNG either. However, my partner who does Partlite on the side as she likes the product so I can obtain many PDF’s containing many images if you woud like more I will post them on my LiveDrive?

                                        they dont have to be particularly big… 30% less is 30% less. Just authentic.

                                          here are the results from independent testing of our test versions of reflate, our first codec for paf.

                                          This is without specific jpg codec included (so pdf’s that contain jpg will not be recompressed to smallest size), and without detection mode for level of recompression needed, which will correct those docx results for instance.

                                          very encouraging :-)

                                              lots of ground work left, but pa-reflate is showing good results for sure, and it is quicker than only competition - stuffit.

                                              by the time we finish 1.0 for release, it should be better than StuffIt in every single case in there, or at least 95%. In fact, with few adjustments, it would already be better overall except for png’s and pdf’s that contain jpegs, because we still have to implement our new jpeg codec.

                                                Remember to keep windows phone in mind when building Engine :D:D

                                                Just kidding… Keep up the good work.

                                                  will the new paf format allow the same actions as zip meaning you can work with files inside a zip file and it will automatically update itself.

                                                  I would like to see recovery like they have with rar. A paf repair tool as well and encryption. sfx program for paf.

                                                    It would be a poor state of development if they couldnt repair there own code. :) but very valid points, and if PA want users to use their new format then they will need to tick those standard boxes you get with competitors formats, would you not concur?
