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
there were some security issues fixed in 7zip:
As it seems, that PowerArchiver and PACL use the 7zip libraries, could you please update them to the latest version?
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.
a) PA always issues a UAC prompt to do this!
b) PA always says there are many errors in PA files.
FAQ: What is optimized 7-Zip compression?
7-Zip Optimized Compression in PowerArchiver
What is it?**
From PowerArchiver 2009, we have added feature called Optimized 7-Zip compression. This feature is currently unique to PowerArchiver 2009.
With Optimized Compression we have tried to solve one of the most important issues that 7-Zip has when compared to ZIP and RAR formats, which is speed and automatic detection of content being compressed.
What does it do?
With Optimized compression feature on, PowerArchiver tries to smartly detect files that are being compressed and assign special compression methods to improve either speed or compression. In the case of text files, it automatically uses PPMd compression for them (instead of LZMA) which has a lot better compression ratio and is also faster. For files that can not be compressed further, it uses different LZMA settings to speed up compression without losing compression strenght. It also works great with solid setting on, which is reccomended as not only it increases compression strenght but also speed as well.
Results are double the compression strenght on text files, and double the speed on files that can not be compressed (mp3, avi, mpeg, etc). Obviously these are the best case scenarios, and in real life usage it depends on data that you are trying to compress.
