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 22.00.09 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.

Some labels in the help toolbar are not translated:

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.
WinZIP AES AE-2 Encryption Vulnerability Found! PowerArchiver may be vulnerable!

WinZIP AES AE-2 Encryption Vulnerability Found! PowerArchiver may be vulnerable!
A vulnerability has been found in the WinZIP AES AE-2 Encryption Method to encrypt and protect ZIP files.
From the documentation I have read about PowerArchiver, PowerArchiver has implemented the same AES AE-2 Encryption Method that WinZIP uses to encrypt ZIP files to maintain compatability between the two programs. Based upon that statement, there is a good chance that PowerArchiver’s ZIP AES AE-2 Encryption Method is also vulnerable.
For more information, please see the link below.

Actually PowerArchiver only reads AE-2, does not create it.
PowerArchiver creates and reads PkWare’s AES encryption and is more secure than WinZips AE-2 encryption, although separate from few WinZip’s inherited issues - problems outlined in that paper are problematic in a sense that a. people will not manage their data securly, b. way compression formats work in general.
Based on my experience, most people are by far more vunerable due to the passwords they use to encrypt their data, which are in 99% cases extremly vunerable to dictionary based attacks and almost never randomized nor is ever correct password key lenght used which makes using 256 bit AES encryption unsecure.
thanks,

I have to use WinZip at work; I hate it! I never liked WinZip and I never will! With all the other programs to choose from, WinZip should NOT be so popular! I don’t know why it is! Here’s just another example as to why it shouldn’t be!
On this subject, if AES (Rijndael) was compromised, PowerArchiver shines because it has other encryption options to choose from. All encryption programs should be this robust; there should ALWAYS be other options to choose from in case one algorithm is cracked! It has happened (DES-56 bit) and will definitely happen again (Rijndael (AES)-128 bit will definitely be cracked in our lifetime).
Which brings up a problem with the PowerArchiver documentation… it states:
“PowerArchiver has 5 different methods of encryption available with Rijndael - AES (default) being the most secure.”
Rijndael is NOT the most secure of the 5 offered. Just because it was chosen as the AES doesn’t mean it’s the absolute best; there were a number of factors in the consideration. After doing some research, of the 5 offered I’d choose Blowfish. If Twofish were offered I’d probably choose that over Blowfish. (Twofish was an AES finalist.) Wish List… Wish List: add Twofish encryption.
In my honest opinion, of the 5 that PowerArchiver offers, only 3 are viable: Blowfish and the 2 Rijndael offerings. But all are significantly better than the previous PKZIP attempt at encryption.
As the Administrator has stated, the password is definitely the weakest link in all of the encryption methods!!!

Just to mention it - AES was not compromised, article talks about how attacker can find connection and might be able to compromise data based on someone sending the file via email, someone else recovering it and knowing something about data from zip header info, which is unencryped. It is all by very, very, very long shot and more deals in absolute security. It very much deals with how compression utilities have always worked.
In that sense, PAE is more secure since nobody knows anything about data encrypted.
Nevertheless, compared to standard zip 2.04g encryption, all these techniques seem as space age technology.
If you are really concerned about security, this would be my priority:
1. chosing coorect, randomized, long password (minimum of 10 characters)
2. securing your own computer against both external and on the site attacks by encrypting important data at all times.In any case, thanks for liking PA! :-)
All everyone should keep in mind that not all data needs to be encrypted, we get few emails per week from people that forgot their PAE passwords for important working material that probably should not have been encrypted at all, such us mid-term papers, etc, etc. :-).
