I hope that despite my poor control of English, you can understand me.
When compressing a file, by default the extension is included as part of the file name. for example, if the file is name.pdf, the compressed file will be name_pdf.zip.
Is there any way for the extensions not to be included in the compressed file name? As much as I have searched I don’t see such an option.
Thanks for your time
I’m using Convert Archives on a local folder of .zip files, converting them to .lzh files, and I’m finding that perhaps 1 in 75 files is actually converting and outputting a file. Even then, the .lzh file is incomplete, missing most of the source files.
The progress bars completes OK, say 75/75 files, but only one .lzh file exists in the output folder.
It seems to be the same with different source and output folders on both local and USB disk - I can’t see a pattern.
The files extract and compress (to .lzh) without issue on their own.
Is there a log file I can check please, to see why PA does not like these files as part of the batch conversion?
Thanks very much, Rich.
I’m experiencing very slow extraction speed of multipart RAR files. For the first part the extraction is super fast but when PA reaches the part2.rar the extraction from there on gets super slow. PA needed for a 6,3 GB multipart archive 30 minutes to extract. I tested then with another program and it just took 70 seconds. I had this slow extraction speed with PA for quite a long time and I always thought that is maybe because of a high compression rate that the extraction would take longer. But it seems that only PA gets that slow.
I have lots of multipart archives that are 10+ GB and with PA it would be really time consuming. Is there any solution to this?
I have powerarchiver licenses for powerarchiver standard and toolbox (and also as a result for pro).
I can successfully register powerarchiver with my pro/toolbox codes, and it unlocks the majority of the content/features. However if I try and create a .pa style archive I get the registration popup saying I need PowerArchiver Pro (if I go to help/about I can verify I have the relevant version and it’s registered to me).

When extracting gcc-arm-10.2-2020.11-mingw-w64-i686-arm-none-linux-gnueabihf.tar.xz , Powerarchiver wrongly thinks some .exe files have a length of zero:

The same archive file does extract properly under a native Linux Ubuntu 20.04 system, or under Windows 10 using the WSL2 Linux subsystem using xz and tar.
I just saw, that on the Website, PowerArchiver 2021 20.00.73 is advertised as latest version. (Actually, the downloaded version says, it’s 20.00.70 in the about dialog)
But it still comes with the “red icon set” for preview versions and has some known unfixed bugs, as I read here.
Is it sufficiently stable to be used on production systems?
Hi I recently bought PowerArchiver and found some bugs and issues that I hit testing some of the features out.
If you are doing a backup and on the compression options screen its default is compression format is PA with no option to change disk spanning. If you change to 7-zip you can change disk spanning. If you change the disk spanning then move back to PA format the field for disk spanning disables but the option stays set to what you changed it to. When you do a backup it will use PA with files spanning but PowerArchiver says that its not a valid format when you open it. If PA can’t really do file spanning then this screen is allowing it.
I have attached an image where the progress bar is in the middle of the CD/DVD/BD Tools screen.
I have a 7-Zip file I created using the backup tools doing an increment backup. It opens and extracts just fine but if you using the Test option PowerArchiver locks up. Link to file: Backup-2021-02-05-20-35-36 TEST LOCKUP.7z
On any Zip/PA/7-Zip process the pause and cancel buttons do not work. You have to hard kill the entire application to get out.
There would be many of us with Intel Processors.
and they have their own optimized zlib algorithm, which can result in more efficiency if used combined with their hardware processor.
Can we get the same Functionality Under Hardware Acceleration Feature?
Zlib is not the only feature that intel has included with their processor, there’s many, which if combined can result in efficient and better compression ratios.
After the batch archiving is complete, and if I click on whitespace of the PA app, I get this error.
I did check for ongoing process and ensured no archives were corrupt, It seems like activity did complete successfully but the error is shown for no reason, and only after clicking the whitespace.
Please see if this can be removed.
I’m using the Kaspersky Total Security.
I have configured PA as exclusion as followed:
and also is set us trusted application
PA Trusted Application.png
My Antivirus likes to scan for everything, and it’s safeguarding behavior is to prevent the access to the file until the file is properly scanned for.
PA when losses the access to file, it is stuck, consumes Resources, and never completes the process or throws any error
PAStarter should also work as PAMonitor:
There should be a monitoring process, at least if I’m using queuing feature, that should check for never ending compression processes and terminate them so the queue can be little bit automated.
There should be multiple attempts at retrying if PA loses access to or is denied, instead of having to see process was stuck for longer duration.
Or, better, save the parameters I used for keeping the files in compression, and automatically restart the whole compression process after termination the same, of same folders and files set, this should happen in case if compression was stuck.
If you use Queue Feature, you are not saving on space, you are just squeezing less.
I did test the same on multiple files, and of different types.
It does have large difference for each large file you are trying to squeeze.
Folders with multiple files, just have no benefits if you use Queue Feature
I am using the portable version of PA2021. After switching from build 58 to 73 I have problems with the color-scheme:
While 58 behaves like expected and showed everything in light or dark colors according to the settings, 73 always shows the lower part of the window in dark colors, no matter whether I select automatic, light or dark.
This happens on a clean installation of 73 as well as on an update from build 58. I have attached two images generated on the same machine at the same time with the same settings. The upper shows build 73, the lower 58. Is it a bug or some changed setting I miss?
Thanks for help!
I currently own the PowerArchiver Select - lifetime free upgrades and support for PowerArchiver Toolbox English license.
This license is active on 1 device. Does the license allow me to activate PowerArchiver on a second device that I own? Or do I need a separate license for that?
Thank you ! :)
I’ve been dealing with an intermittent explorer.exe crash for 5-6 years now. It happens randomly and will usually occur multiple times within a single session of an hour or two on my machine when manipulating files through Windows Explorer. explorer.exe is the only thing that ever crashes, so it’s not hardware IMO. I’ve done all hardware diagnostics and RAM is good. I’ve even swapped out motherboards with different brand and even the exact same one and it still crashes. sfc /scannow indicates system files are fine. I’ve done multiple reinstalls of the OS with no positive results. This crashing has happened on Windows 7 64-bit and Windows 10 64-bit. It seemed to get more frequent with Windows 10 after upgrading last year. I’ve also been using PowerArchiver throughout that time period (upgrading over time with new releases). I recently disabled all non-Microsoft extensions via ShellExView and saw no crashes for about 10 days, which is really unusual. I turned back them all back on after 10 days and saw another explorer.exe crash within the hour. So I disabled all 32-bit extensions and saw another crash. Following that I disabled all the PowerArchiver shell extensions and haven’t seen a crash after a day of heavy usage manipulating files within Windows Explorer, which doesn’t happen for me. The crash dumps I’ve captured don’t seem to indicate PowerArchiver is involved but I have a hunch it has something do with PowerArchiver shell extensions. The system even feels smoother with the PA extensions disabled. Windows 10 reliability monitor always has the same type of problem:Description Faulting Application Path: C:\WINDOWS\explorer.exe Problem signature Problem Event Name: BEX64 Application Name: explorer.exe Application Version: 10.0.17134.165 Application Timestamp: 4031a9f8 Fault Module Name: StackHash_e78e Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Offset: PCH_8D_FROM_ntdll+0x000000000009AA54 Exception Code: c0000005 Exception Data: 0000000000000008 OS Version: 10.0.17126.96.36.199.256.48 Locale ID: 1033 Additional Information 1: e78e Additional Information 2: e78e327659b46c9a0c6916396b253cbf Additional Information 3: cebf Additional Information 4: cebf952c5db535ae7880488aafce55d9 Extra information about the problem Bucket ID: 1a57e4e784fbc735c231c68bd88581a9 (1311047270476906921)
I know this is a very nebulous explanation but is there any way to link this up to PA shell extensions as the cause? I can provide the crash dumps and additional information if necessary.
