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.
Compression methods
-
may someone explain the compression methods in ways of situations when one is best of the others? tar seems to be best (there are multiple types of tar?)
sorry all the methods that PA is capable of and i don’t know which to choose in cases

Tar is the lowest of all the types…it basically binds the files together without actually compressing them.
7-zip is the newest and most powerful of the compression schemes…if you want high compression ratios (smallest files), use 7-zip.
ZIP is the most widespread archiving format on the internet. While it generally gets on the low end of the compression levels, almost everybody already has software to open Zip files. If sharing files with friends you may wish to use ZIP.
GZipped and BZipped tars are basically tar files with compression added. Theyre used much more commonly in Unix environments than Windows environments. Compression for these is generally better than ZIP but worse than 7-Zip
These are the most popular types. Other types are used more sparsely and rarely have benefits thats outweigh the above.

i’ve done a couple tests putting multiple files together using .7z and it was a larger size than when using .tar for a given selection of files. i don’t understand how .7z has more compression than?

for high compression
7-Zip
don’t forget to check “Solid compression” before compressing your filesfor exchange with other users
ZIP
because every packer can handle ZIP -

The only time this can happen is if the files you are “compressing” are already in a compressed format (which you may not have realised)!
E.g. Jpeg, Mpg etc.
Note some exe files are also “compressed”.If the file are uncompressed, then any compression format will give a smaller resultant size than TAR - because TAR does not perform compression.
E.g. Try with multiple text files, word documents, bmp files etc.With these, even using “fast” compression will produce a smaller archive filesize than TAR.

thank you for the informative replies; that was helpful. thank you :)
