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.
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

Hi there,
there were some security issues fixed in 7zip:
https://www.zerodayinitiative.com/advisories/ZDI-23-1165/

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.
Add & Replace vs. Move
-
I noticed that two of the file types (7-zip and Tar) do not support any options other than “Add and Replace” when creating an archive. I’m curious why the Move option isn’t available. As far as I knew, the only difference was that after creating the archive, the original files were deleted from the disk. But to me it doesn’t make sense that this wouldn’t be supported under Tar and 7-zip…so what’s the real difference?
-
It is because tar and 7zip engines do not support move option. It has to be built-in in the engine, or it would be nearly impossible to properly verify that file has been compressed properly and that PA can safely delete it.
thanks,

Alright, thanks. Additional question then, how is the the free 7-zip compression program from sourceforge supports Update and Add and Freshen options in addition to add and replace, yet PA only has add & replace for 7z? I assume they all use the same compression engine since it’s open source… Or is this another thing that will be available in a future release when the dll is updated?

Currently we can not use move function. It is possible that we could use it with new support in 9.5, but I am not sure yet. We would also have to test it extensivly to make sure it works only when it should, so even if we are able to add support for it, we might not if it is not 100% reliable.
In general, if it was up to me, we wouldnt have move function at all, because there is always an possibility for end user to lose their data.
Obviously Igor Pavlov who created 7zip has a lot more insight into how it works than what we do, so 7zip support will always be the best inside 7zip itself :-).
thanks,
