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

pa-convert-zip-2.jpgUsing the “Store” method sometimes creates a .zip file; I have seen it happen just now, but I cannot reproduce it.

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.pngThe 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.

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 versionPA 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 windowsOn 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.

I recently installed PA 2021. But the PowerArchiver Starter, for my backups, keeps running at high CPU usage, I have to keep killing it, its running about 46% constantly.
I have Windows 10 Pro, 20H2, build 19042.662
Any ideas would be helpful.
Thanks

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?

Hi,
You can obtain the original file from here:

For Lenovo Y50-70 win 7 x64 bit, power management, get lenovo energy management
Run the exe it will extract the installable drivers to C:\drivers
I tried to compress the whole folder using PA using following parameters:
Extreme, strong optimize.
image_2020-12-27_195344.pngThis resulted in negative compression.
However same file is compressed by 7zip alpha, with positive compression:
PA Negative compression.png
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.

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.

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. -
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?
Thank you!

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.

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.

On PowerArchiver 2021 (20.00.60) and windows 10, Both options in the windows explorer shell extension, “Compress to …zip” and “Compress to …zipx” create a .zipx file. ¿Its this intended?
-
My slow ring still reads as 19.00.59… will it ever offer an update to 2021 or is that something I must do manually?

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.pngI 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.pngI 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! -
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’ve made the sections of the output bold to indicate where the typo is.

I’ve found a bug when extracting files from a 7ZIP file, specifically when you tell PowerArchiver to extract only some files and folders from it. This is where the bug exists. You can tell PowerArchiver to extract only certain files but then it proceeds to extract the whole file and not just what you wanted.
-
Sorry if I’m asking this in the wrong place.
Can Powerarchiver create images of entire drives (e.g. C: system drive) to create drive image backups?
Thanks,

Good day,
I just stumbled across this story about the use of brute force techniques to crack passwords.
What hash algorithm do the encrypted forms of zip, 7z, and Rar use? Knowing this may make helps users decide which format is most secure.
I gather, too, that you intentionally slow down the unencryption of PAE2 files to avoid brute force attacks. Correct?
Having some of this info can guide future decisions about which file types to use for delicate data.
-
yes, both pae and pae2 are much slower to brute-force due to design… i know sometimes people complain having to wait for whole archive to be decrypted before “wrong password” is shown but it works well in this case.
Both 7zip and ZIP AES encryption use sha256 hashes. Together with proper length not dictionary based passwords, it is still extremely hard/slow to brute force.
Of course, lets put this straight - article talks about linkedin using sha1 but of course as article mentions, this is completely unusable against real world online services where it is not possible to guess password more than few times, let alone 100 billion times per second.
-
PAE2 also use a sha256 hash?
-
pae/pae2 require full decryption of the file first, so basically they use aes 256bit. they can not quickly check hash to see if guessed password is correct.
