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:

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.
Any way to Compress media files?
-
Is there any way to further compress media files like AVI or WMV. Or are they already too compressed (no white space)
-
Yes they can be compressed.
Which format to use depends on many factors (e.g. single or multiple; codec used in file). Also, which is more important to you - speed or final size.I suggest you do some testing with your own files to decide …
Try these formats - 7z; Tar.gz; Tar.bz2Also check cab and bh (but remember there is 2GB limit with these formats).
-
there is no way to compress them further in lossless compression utility… only way to lower the size is to recompress the video itself but that takes long time and you need some kind of video utility that will transcode the file to some more efficient format/codec…

Quick test:
1 Folder (AVI Movies)
Windows explorer properties 6 files
Size 234MB (245, 792, 977 bytes)AVI Movies.tar.bz2
Windows explorer properties
Size 193 MB (203, 335, 440 bytes) :pAre you saying BZ2 is a lossy compression :confused:

Thanks for the insight I will run some tests. Even 25% would be great on a 2gb file.
Thanks, Alan

Even 25% would be great on a 2gb file.
As both I and spwolf “implied”, that most likely will not be possible with a single video file. Still, try it and see.
