For example:
Download this ZIP file: http://dslstats.me.uk/files/dslstats32W-6.5.zip
Everything in the ZIP file is in a directory “dslstats32W-6.5”.
However when I extract using right click “Extract Here” the name of the directory created is “2W-6.5” !
I am running PA 22.00.09 on Windows 11. I have seen the same happen with some other kinds of archive too.
Hello!
Is there currently no portable version of PA2023 available?
(When) do you plan to release one?
Thanks!
If I compress a folder to a .pa using right click, Compress to folder.pa and use the new Windows 11 menu then the Options, Configuration, Miscellaneous, Use normal relative path setting is always enabled.
But I like this option disabled so I have to use the old style menu in order to get PA to compress a folder in the way I wish.
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

PA 22.00.09 shows a nag screen, when I try to open some setting windows. I have already PA 2023 Toolbox and PA shows, that it’s licensed in the info dialog.

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.
Hi there,
there were some security issues fixed in 7zip:
https://www.zerodayinitiative.com/advisories/ZDI-23-1165/
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.
Compressing Video Files
-
Ok, I have noticed from time to time while on usenet, I have downloaded some videos that were compressed at unbelievable compression ratios. Example: I downloaded a video that had an actual size of say 100 megs. It was compressed down to about 18 megs, WOW.
I have just about tried every compression program on the net and I can’t seem to find one that does this. How do these people do this?
I have also tried uping the compression to Maximum, or Ultra etc… I have went to lengths to encode my videos from RAW AVI to just about every other video format in the world, and then compress them with every archival program I could find and I can’t seem to obtain these outragously low file sizes after being archived.
Could someone please tell me how these guys are doing this?
Another example is that I downloaded a 690 CD that was compressed to 280 megs. WoW again!!! This was a DivX video.
-
I have never seen compression like that before. In fact the opposite. Over the last couple years I have downloaded numerous vid’s that were: RAR, ZIP and 7Zip and the compression ratios were at 0 to 2 percent.
All of these videos were either mpg or wmv. So I am guessing that each file format will have different compression ratios. Things like audio bitrate must be a factor.
Its interesting and I would like to read about other peoples experience with this topic.

Well, you have the files, what was the compression format used for the files you downloaded?
-
lossy compression or lossless? I dont see how can something compress an divx file from 690 MB to 280 MB - that would mean that divx format itself is leaving at least 400 MB of extra, unneeded data in the file :-).
on the other hand, lossy formats like divx can always compress better not only because they are specific to one type of files, but because they are lossy - you loose quality for smaller size.
-
I was just testing WMV and 7Z. I compressed a 163 MB WMV to 7Z (Max) and the compressed file is 164 MB. It actually came out slightly larger in file size.
Using NTFS on XP and the size on disk is larger for 7z as opposed to uncompressed WMV.
-
Ok, All of the video files that were compressed had the *.zip extension.
I have been doing alot of research and I have noticed in most of my findings that you can actually “OverZiP” , kinda like “OverClocking” a compression.
WinZip & PKZip both have commandlines. Using the standard compression ratio’s in the GUI is not enough and you will not acheive the most ultimate compression. In addition to this, I found a program called, “ZipMax” found here at: http://www.clrmame.com were you can actually rezip a zip into a better compression using a totally different algorithem. According to the author, most zip archiving programs doesn’t compress to the max, even with max chosen. They breakoff at a certain point.
There is also another method I am just now finding out about, and this seems to be pretty cool but a little bit time consuming but maybe not once you get the hang of it. The program is called “KZIP”. and can be found here: http://www.compression-links.info/Link/1913_KZIP.htm
Kzip is command line only and I have yet found documentation on it and I’m assuming you would use commands of that found for PKzip.
I wonder if anyone has created a special zip program dedicated and geard towards file formats such as mpg,mpeg,rm,DivX,AVI (compressed),wmv…etc…?
I will continue with this endeavor until I find a solution. But I would bet my best bet is to loose the GUI and stick with commandline zipping methods.
EDIT: ADDED
I just found this website with a zip program dedicated to “multimedia” files. I’m going to check it out.
-
None of that has absolutly nothing to do with compressing divx from 700 mb to 280 mb.
Zip/deflate compression will not get you anywhere. In fact, since all these multimedia formats are lossy and already compressed files you will not be able to compress them furthermore by any format, let alone something like zip.
Basic things you need to know:
a. Lossy compression - compression format where you loose quality to gain extra compression strenght (divx, mp3, etc).
c. Lossless compression - compression format where files are left exactly the same. Zip, 7zip, Rar, Ace, etc.From that, we go to facts:
a. Good lossy compression will by far outcompress lossless compression.
b. You can not improve upon lossy compression by lossless compression afterwards (in this case, ziping an divx).This is why you can choose quality of MP3 files for example - more quality, higher size, less quality, smaller size. There are lossless multimedia compression formats, however their sizes usually are 3-4x larger than high quality MP3’s so they are seldom used.
-
p.s. “overziping” does not exist. Same sizes are achieved by both command line or GUI, other than possibility of some issues with software in question or completly different software code.
Another thing is that these are PowerArchiver forums - please refrain from mentioning/linking to other compression utilities.
thanks,

i’ve tested the software and better results than anything i’ve seen before

Oops, read this before looking at that - http://www.c10n.info/archives/415

i only tested archiving the files up not extracting them.
we should have a list of bad compression foemats like this as it looks good on the outside but the inside its totally not very good.

I am closing this thread. David, you know our policy better than most. Thank you!
