Hi,
I’d like to propose an improvement for password protected archives.
Actual behavior is:
If I open an archive, which is password protected and make a typo in the password dialog, I’ll get the message, that the password was wrong and I end up with an empty window. I need to reopen the archive to be able to enter the password again.Improved behavior:
Tell me, that the password was wrong and give me the chance to enter the correct password to decrypt the archive. -
Hello!
I know I have been asking for this feature some time ago, but as nothing has changed let me ask again:
The ZIPX-format offers an algorithm, that compresses JPEG-files by about 20-30%. Please add compression (packing) support for this in ZIPX-archives to Powerarchiver. Extraction of JPEGs packed into ZIPX by this algorithm is already supported by Powerarchiver for a long time, so it should not be difficult? Or is it a licensing problem?
Thanks! -
Hi,
I’d like to suggest, that the correct archive type is (always) selected, when adding files by drag & drop to an archive.
This is already happening if the archive has the correct extension. For example, if I’m adding files to test.zip, zip will be selected. If I’m adding files to test.7z, 7z will be selected as format in “Add dialog”.
But this won’t be working, if the archive has not the “right” extension.
So XPI files (Firefox addons) for example are ZIP files. PowerArchiver opens them without any problems, but if I try to add file by drag & drop, PowerArchiver won’t auto select “ZIP”, but use the last selected archive format, while PowerArchiver already knows, that I’m trying to add files to a ZIP. -
I love this, only there is one problem. The UAC elevation feature does not extend to Mount Image option in the add-on software PA provided. It is most annoying whenever I am on highest UAC settings and I mount an ISO, every time I open and create a virtual drive UAC appears. I also do not want to completely disable UAC.
Is adding UAC elevation for mount image feature possible?
-
The now defunct Bulkzip had Nanozip (nz) as an option this would be great to have for compatibility with my .nz files, so I don’t have to install Bulkzip separately.

Hi.
I noticed that when I want to run the Virtual Drive for the first time inside the PowerArchiver Burner it prompts to download it form the internet.
I was wondering, would it be OK to include this utility straight into the offline installer to be able to set it up locally?
Thank you!

How about recognising a few more (or all) of the file formats that are basically renamed zip files and treating them is if they are zip files.
For instance Android .apk files are just renamed .zip files.
Libreoffice/Openoffice ODF documents are all, as far as I am aware, just renamed .zip files. (.odt, .ott, .ods, .ots, .odp, .otp, .odb, .odf etc.) -

Would it be possible at all in some future version perhaps, to have a “find file” function?
Reason I ask is that I was looking for a certain file I knew existed in an archive, but I had to unzip it then use another tool to find the file. It would have saved that extra step if that function existed in PA itself. -
Hi.
Is there a way to enable the user to encrypt the files inside a ZIPX archive that has already been created?
This could save time for large archives that the user may need to encrypt at a later stage or that he/she has forgotten to enable encryption before creating the archive,
Thank you!

Hi.
I would like to see a new feature implemented: a ‘Fast Extract’ Mode.
Currently PowerArchiver extracts files to a temporary directory and then moves them to the target directory chosen by the user. At least via drag and drop.
This can be both time consuming and needs free space on the system drive for large files.
Is there a way to directly extract files to the target directory with PowerArchiver?
And if not, can a feature like this be considered for future updates?Thanks very much!

Hello.
I believe it would be useful to implement Serpent-256 encryption for PAE/PAE2 formats, even though PowerArchiver offers strong encryption ciphers already.
(deleted part advertising other software - admin)
Do you think this will be a useful addition?
Thank you for the consideration!

Hello!
I think it would be a great option to make the portable version of PowerArchiver compatible with PortableApps (i.e. adding the necessary files and folders to integrate it smoothly into their structure).
I own various other commercial programmes which -when installed in portable mode- offer to make the becessary changes without needing an extra installer or the official PortableApps repos.
Thanks for opinions or perhaps even a realization of this.

Presently, PowerArchiver 2019 (any build) cannot rename PBS filenames by single clicking on such entry or right-click menu has no “Rename” feature!
Hmm, even pressing F2 on selected entry does nothing :(

Please add support for ownCloud / Nextcloud, thanks.

7zip need better ratio in PA
-
I tried with many options in 7-Zip to improve my compression ratio and I think that it will be good if PA Developers add this options to PA.
And noone archiver test crush new PA compression ratio in any tests.I think that this formula should be use in Ultra mode
or You need add this formula in Extreme Mode ;]And this formula for Parameters bring the best compression ratioand about increase PA ratio about 1-4%, and for me is big diffrence
[b]x=9 s=on f=on hc=on hcf=on mt=on a=1 mf=bt4 fb=273 mc=1000000000 lc=0 lp=0 pb=0[/b]
and some explanation:
x=9
(level of compression)
options: x=[0 | 1 | 5 | 7 | 9] ,
higher number=better ratios=on
(solid mode)
options: s=[off | on]
on gives better ratiof=on
(filters for executable files: dll, exe, ocx, sfx, sys)
options: f=[off | on]
on gives better ratiohc=on
(archive header compressing)
options: hc=[off | on]
on gives better ratiohcf=on
(full archive header compressing)
options: hcf=[off | on]
on gives better ratiomt=on
(multithread mode)
options: mt=[off | on | {N}]
on gives faster processing time**a=1
**(compressing mode)
options: a=[0|1]
higher number=better ratiomf=bt4
(Match Finder for LZMA)
options: mf={MF_ID}
bt2 = d9.5 + 4 MB = Binary Tree with 2 bytes hashing.
bt3 = d11.5 + 4 MB = Binary Tree with 3 bytes hashing.
bt4 = d11.5 + 4 MB = Binary Tree with 4 bytes hashing.
hc4 = d7.5 + 4 MB = Hash Chain with 4 bytes hashing.
the bt=4 provide the better compression ratiofb=273
(fast bytes for LZMA)
options: fb={N} where N=<5,273>
higher number=better ratiomc=1000000000
(cycles (passes) for match finder)
options: mc={N} where N=<0,1000000000>
higher number=better ratiolc=0
(literal context bits (high bits of previous literal))
options: lc={N} where N=<0,8>**
lower number**=better ratio**
lp=0**
(literal pos bits (low bits of current position for literals))
options: lp={N} where N=<0,4>
lower number=better ratiopb=0
(pos bits (low bits of current position))
options: pb={N} where N=<0,4>
lower number=better ratio -
noone intrested add Extreme mode to 7zip compression to improve ratio :(
-
I must admit I use 7zip for 90% of all my compression at work due to using Spreadsheets, Databases and word documents.
If there is an improvement to the compression ratio then its worth looking into.
However, it’s down to the PA Crew and the time it would take to develop and maintain for on going versions of 7Zip and PA.

More important - what is speed difference? 50% slower? :-)

Nope :p, but too my surprise it was faster than normal settings in 7-Zip
And some test on about 350 files (doc, wav, mpeg etc.) in 1 folder:
uncompressed folder
335 MB (352.235.162 bytes)compressed in PA2007b9 (soild, Ultra mode)
224 MB (235.877.605 bytes)
10min 58 sek :D PA OWNS!!! :cool:compressed in 7-Zip 4.44beta (soild, Ultra mode, Dictionary 48MB and other settings on default)
224 MB (235.136.186 bytes)
14min 35sekcompressed in 7-Zip 4.44beta (soild, Ultra mode, Dictionary 48MB and parameters like x=9 s=on f=on hc=on hcf=on mt=on a=1 mf=bt4 fb=273 mc=1000000000 lc=0 lp=0 pb=0
202 MB (211.952.354 bytes)
14min 17sekthis test was performed on PIII 900Mhz, 768MB RAM
and I think that settings for 7zip in PA2007 + Yours super mega tweaks improve compression speed = Super PA 2007 with the best compression ratio on the world :p
You may test normal PA2007 settings (Ultra, Solild) and my setting on PA2007
and You see what settings are better, because I dont have access to developer console :p
and I dont know what settings are better, because this test was performed only in 7-Zip -
Here is the problem - if we use same settings as 7zip, speed will be the same :-).
So it is better to have 2% worse compression and get a lot faster speed….

Yep, I agree with You :p
But I was thinking that, PA use only modified code with some compilation improvement for todays procesors ;)
Well, this topic should be closed now :cool:

Hmm…packing
Vista x64(Atlon 64 3500+), PA 2007 beta, 7 zip 4.45 beta x64
PA- 1m24s
7z 4.45- 1m08s
-
there are several things that might go there - like did you try compress each several times? For instance if you try 7z later, it will be faster since Windows cached the file already.
In our tests, it is 10% faster, and gets 1% less compression, with files that can be compressed (unlike driver installation you tried)… Testing can also vary based on type of file you are testing as well…
-
In my tests in same cases(dif. files and queue) PA did best compression, but ALWAYS bad time…
I think it may be only for Vista x64… 7 zip - 64bit!!! and PA only 32 bit…
