For example:
Download this ZIP file: http://dslstats.me.uk/files/dslstats32W-6.5.zip
Everything in the ZIP file is in a directory “dslstats32W-6.5”.
However when I extract using right click “Extract Here” the name of the directory created is “2W-6.5” !
I am running PA on Windows 11. I have seen the same happen with some other kinds of archive too.
Hello!
Is there currently no portable version of PA2023 available?
(When) do you plan to release one?
Thanks!
If I compress a folder to a .pa using right click, Compress to folder.pa and use the new Windows 11 menu then the Options, Configuration, Miscellaneous, Use normal relative path setting is always enabled.
But I like this option disabled so I have to use the old style menu in order to get PA to compress a folder in the way I wish.
Just tried using the Modern (Windows 10) Icon set and seeing a few missing icons in both PowerArchiver Burner and PowerArchiver Encryption screens . They are all there in the Minimalistik icon set and the only difference I can see is the former is blue and the latter grey. In version 22.00.9

PA 22.00.09 shows a nag screen, when I try to open some setting windows. I have already PA 2023 Toolbox and PA shows, that it’s licensed in the info dialog.

I’m looking forward to deploying PowerArchiver 2023 to my users. Can you tell us when the MSI will be available for download and distribution?
Thanks.
Hi there,
there were some security issues fixed in 7zip:
https://www.zerodayinitiative.com/advisories/ZDI-23-1165/
https://www.zerodayinitiative.com/advisories/ZDI-23-1164/
As it seems, that PowerArchiver and PACL use the 7zip libraries, could you please update them to the latest version?
Hi,
From where I get PAVD2023.EXE? PowerArchiver 2023 tries to open it.
But it seems, it tries to download PAVD2021.EXE.
Thanks
I noticed that the version of ZPAQ used is older than the latest released 7.15 https://mattmahoney.net/dc/zpaq.html also there seems to be a newer fork that adds several features https://github.com/fcorbelli/zpaqfranz
It would be useful to implement this latest version (it also maintains the same syntax and behavior as the latest official release if used the -715 flag) and add when opening a zpaq file a choice of the version of the files to show (e.g. as dummy folders represented the various versions present). Since any previous changes are stored with this format, it is possible to extract a snapshot of a certain date/version.
If I open a password-protected zipper file (created with WinRAR but I think that’s irrelevant), open it with PowerArchiver and run “Remove Encryption” on the same file, then reopen it and add a password with “Encrypt Archive,” the resulting archive will be protected with the old ZipCrypto algorithm and not AES as indicated.
(this can be verified, for example, by trying to open the archive files with Windows Explorer, which does not support the AES algorithm)
PA 21.00.18 running on Windows 7 64 bit.
I made a big .PA file and thought I’d check it was made correctly with Menu / Actions / Test.
Discovered:
a) PA always issues a UAC prompt to do this!
b) PA always says there are many errors in PA files.
Bug - Compression method 99
-
When adding a file to a zip archive from Action-Add, when Method ‘Deflate’ is selected, it’s saved into the archive as ‘compression method’ 99 (unknown) instead of 08 (deflate). This causes issues with Windows Explore native Zip reader, it can’t extract the file.
-
Same goes for right-clicking on a file, selecting ‘Compress with Options’ (we encrypt with AES128, if that matters). The file is also method 99
This is the debug info `zipinfo’ gives me when I parse the archive’s header.
The central-directory extra field contains:
- A subfield with ID 0x9901 (unknown) and 7 data bytes:
02 00 41 45 01 08 00.
- A subfield with ID 0x9901 (unknown) and 7 data bytes:
-
can you please confirm what version of PA and what version of Windows? Also, what did you use to check compression method?
I quickly checked and it seems fine… shows as deflate and opens up in Windows Explorer.
Thanks!

Now I see your 2nd post… so basically reason this does not work is that Windows does not support AES encryption… the library that they use is very old and company went out of business, thus their zip support is limited.
Just to make sure something new did not happen, I checked with WinZip, SecureZIP and few other ZIP programs and Windows will not read any of them… I was using latest 8.1 release.

My apologies, I’m new to this whole “reporting a bug” thing.
PA 15.01.05
Windows 7 SP1, full updates.This issue has been reproduced on 2 separate systems, both are the same OS and PA version.
I can reproduce this by using any of the AES encryption ciphers, it doesn’t happen with the old 2.04g cipher and non-encrypted files.
This is an example file. Explorer isn’t able to open the first AES file.
http://hackthegibson.net/tmp/test%20file.zipOn the broken AES file (exact duplicate of the other AES file), also notice the ‘packed’ size is different and the ‘CRC’ is blank in PA.
Everything works properly when I drag-drop the file into the archive, Windows 7 can read AES128.
-
I’ve pasted the full output of `zipinfo’ to http://pastebin.com/Vsvbmq9w
Look at file #3:
test file encrypted aes128.txt
compression method: unknown (99)
32-bit CRC value (hex): 00000000While the functioning AES128 file, #4, reads as:
test file encrypted aes128 - WORKS.txt
compression method: deflated
32-bit CRC value (hex): 20e267dd -
can you cab that file and send it to us via email? support@conexware.com
I cant download it from that site for some reason.Are you sure that zip crypto is not being used in the case where it works? You can check method in PowerArchiver, right click on any of the list view columns and click on Method.
Thanks a lot!
-
All the files show as “DFLT-X”
As requested, the cab file has been emailed.

thanks - I will check it out and let you know.

Chris - how did you create one that works, via drag and drop? There seems to be a problem there, since that file is encrypted using zip crypto method (from 2.04g spec).
Keep in mind that there is a central and local directory in zip archive. Now our compression guys are already out, but I would not be surprised if this is done for compatibility reasons, so you would not try to enter password for unknown encryption dozen times.

i have written bug report for drag & drop - zip crypto creation… this should be corrected in next upcoming release, which should be quite soon. I will update this thread once we have that ready… thanks a lot for the report.
I am also setting up Win7 test computer to see if it actually supports aes, unfortunately i dont think thats the case - it was likely just confusion due to the bug in drag and drop.
thank you!!!
-
Correct, it worked when I used drag & drop. Thanks for finding the issue!

sorry about that Chris but big thanks for the report.

Here is the updated PA 2015 15.02.1 which fixes the bug with zipcrypto instead of AES when using drag and drop:
