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-23-1164/
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.
Creation of large spanned archives is slow

Hmm, different results, but definitely not optimal. After six minutes or so, PA created a 17GB tmp file (from compressing 30GB of source files). The progress bar was at 100% and PA continued to do something for 10 minutes or so. I then saw a z01 file appear in the destination directory (I specified to split the archive into DVD sized chunks). It continued to thrash for another 10 minutes, then a z02 file appeared. I finally canceled the operation as I had to shutdown the machine.
If this is as designed, more optimization is needed. For example, Winzip creates the z01, z02 files as the compression operation proceeds and you don’t need the intermediate tmp file (which basically requires you to have double the space) plus Winzip effectively does the operation in half the time since it doesn’t create the tmp file, then split up into the size specified in the options panel.
When creating a single zip file, I was able to create a zip from the same 30GB source with no problem (took about 6 1/2 minutes). I tried writing directly into the zip and not selecting that option and had no problems.
Hopefully this makes sense. Let me know if you need more info or want me to run more tests.

thats completly different issue than original one, i noticed it was doing that, it was workaround as 2 days ago multivolumes were not working at all.

Agreed. At least it is making multi-volumes now, just not very optimally :).

especially on i7, where normal deflate is blazing through :-)

move it to new thread, closing this one, thanks!

err, closing old one :)

We will check progressbar issues, but currently the way spanned archives are created will not be changed in 11.50 for sure - they are generated in two steps - first in temp folder a complete zip is created and then that zip is spanned.
-
If the splitting wasn’t so slow, this may be tolerable, even with the double disk space issue, but Winzip, even single threaded, makes split zip’s much faster using the same source files as the new PA does, even with the benefit of an i7 cpu on the front end.
-
splitting itself is not slow, it is basically double action which is why it is slower than single action… its limited by the speed of hdd.
if it was done at once it would be much faster of course.
-
unfortunatly right now we can cry about it and make it prettier :).
Question is how much of MV are you using vs single archive to see how much the problem affects you.
-
we found some situations where there would be double the copying, and we made sure that does not happen now.
so it is still compressing and then splitting, but it might be faster for you now.
