For some reason, the PowerArchiver functions in the Windows 11 context menu no longer work after the last Windows Update. Only the functions in the classic context menu function as they should.
I’ve tried uninstalling PowerArchiver and using RevoUninstaller to remove all bits and pieces that were left behind and did a clean install of PowerArchiver, it didn’t fix the issue. Other items in the Windows 11 context menu work.
I installed powarc-macos20001.dmg and I am attempting to create a password protected zip file. When I create the zip in the UI it doesn’t write the file to the destination folder. No error message is displayed. The PA app has full folder permission. I’m new to Mac, but have been running PA on Windows for a long time.
Will there be a new version of the Mac version soon?
Hi! I came across an issue when I tried to uninstall PowerArch 2013. I got an error “The specified account already exists” which broke the process. I got the same error when I tried to install the current version, without uninstalling the previous one.
So I can’t uninstall and I can’t install PowerArchiver. Any suggestions? OS Windows 8.1 x64.
This appears to be happening again with the Power Archiver 2022 shell extensions.
When I have Use Explorer Shell Extensions enabled in Power Archiver Configuration and right-click on c:\Users\username\Start Menu, (hidden Junction file), File Explorer crashes.
I have version 21.00.15 (03/2022) 64-bit installed in Windows 10 Version 21H2 (Build 19044.1826).
The online update feature within the program suggests there is a later version than the ‘.17’ available on the web site. But clicking either download or update just reinstalls version .17.
Either there isn’t an update OR
the “download” and 'update" links should be repaired.
When you click on the Buy Now link, you come across four tabs - Home or Work, Enterprise Unlimited, Educational Discount, & Gift Discount.
What is the difference between a licence purchased via Gift Discount and a Home/Work licence?
Also, how can I renew the PowerArchiver Select plan a year after the purchase? Will it remind me automatically?
I’m running PA 21.00.17 64-bit on a 64-bit i7 desktop with W10 Pro, latest version. This 32gb of installed RAM.
As I use the PA pbs system for a number of scheduled archiving operations throughout the day, PA Starter is set to load and run at system startup.
In the course of trying to identify some causes of slowness and bottlenecks in other processes, I notice that PA Starter (PAS) always runs at between 11% and 15% of CPU (see screenshot), usually at about 12-13%. This is by far the highest demanding process on the system, as shown by Task Manager. In Performance Monitor, PAS Average CPU is 8.32, with every other process at less that 1 i.e. in decimal places only.
Task Manager also shows PAS Power Usage as “Very High”, and is the only process shown thus.
I have looked again at the information about PAS at https://wiki.powerarchiver.com/en:help:details:powerarchiver_starter, which was last modified in 2016. The article states a low memory usage for PAS of 784k, which is fair enough, but it is the large CPU overhead which is of concern.
It is of course possible to change the PAS priority, but this has no effect on CPU overhead.
However, is it possible to change PAS, which is required only at intervals to initiate PA scheduled tasks, from consuming so much system resource for every moment of the day?
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?
Optimized method not really optimized….
I’m using the latest build of PowerArchiver 2016 16.00.69. I am the kind of person who loves the best compression possible within a fair time.
I have tested the 7-Zip option and have set it to Optimized method and Ultra (memory req.) compression and have solid archive enabled.
I expected this to give the best possible compression, but this is not so.
For example, on the following file “Ashampoo Anti-Virus 1.2.0.exe” which is 158,458 KB, I get the following results:
7-Zip (Optimized method) -> 159,945 KB
7-Zip (LZMA2 method + everything else same) -> 157,863 KB
I expected that the Optimized method would take into account the big initial file size and use the LZMA2 method to get the smallest possible compressed file.
Why isn’t that the case?
Also, just a suggestion. Put in an option that uses all methods automatically and performs the compression multiple times and then leaves you with the best compressed file possible for that format (7-Zip, RAR, CAB, etc).
For example, if I select to get smallest file with 7-Zip, it does the compression several times using the different methods and then leaves me with the smallest file it could end up with after its all been run.
confirmed and noted!
thanks for taking the time to provide the details
Please provide updates as something more comes to light regarding this.
Can confirm at least in 17.00 problem is fixed. Nevertheless, ratio on Optimized compression, is not as good as in the official 7-Zip, so I will fill a new post.
try the same files with .pa format now :)
I have compressed full PowerArchiver x64 portable in my SSD disk, so it is easy for you to reproduce.
- Uncompressed size: 176.473.679 bytes.
- 7-Zip 17.00 Ultra LZMA 128MB fb273 myx=9: 28.330.063 bytes.
- PowerArchiver 7z 17.00.69 LZMA Ultra: 29.060.624 bytes.
- 7-Zip 17.00 Ultra LZMA2 128MB fb273 myx=9: 28.323.572 bytes.
- PowerArchiver 17.00.69 7z LZMA2 Ultra: 29.062.095 bytes.
- PowerArchiver 17.00.69 7z Optimized Ultra: 41.579.382 bytes.
Take a look at the bad results with the Optimized profile, and also at the equivalent PA implementation, being slightly worse than the one in 7-Zip, meaning that the library used or its parameters, are subobtimal.
By the way, same with PA format, excellent results:
- PowerArchiver 17.00.69 pa Extreme Optimize Strong: 27.114.421 bytes.
