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.
WinRAR 5 has a rather useful option in some cases, which is to be able to create an archive by replacing identical files with a reference to the first occurrence (hardlink) within the archive.
In case you choose to convert the file with PowerArchiver to another format, however, the resulting archive does not have all the files. It does not consider those that were present as hardlinks.
If you do a normal extraction of the RAR archive instead, even with PowerArchivier, all the files are extracted correctly.
When adding to a file archive, and selecting for example PA format, strong optimization method, extreme compression. In the Advanced Options section you change to Automatic, EXE Filter and PDF filter . You return to the main section and save the Profile. When you then reload the profile you do not have the Automatic options of EXE Filter and PDF saved there.
I noticed that instead if you change other options they are saved correctly (except for the Filter box values).
Also among the various changes to the advanced options you click the “Calculate RAM usage” button the value seems to be added to the previous one. You can see it for example just by clicking the button twice in a row, the value changes. Edit: actually after many attempts now it seems to write a stable value (it does not change with each click). Maybe a synchronization problem in the calculation?
Used PowerArchivier 2023 but there is the same behavior with the 2022
Unsolved Cannot compress big files to .PA archives

You cannot compress big files (tested with a file bigger than 330MB) into .PA format unless you start PowerArchiver with Admin rights.
Otherwise, this error is shown:
If you compress a small file (say 8MB), then the .PA archive is created without issues.
I’m not sure what file sizes hit these ‘small’ and ‘large’ file limits.
Repeat the same test, but instead of creating a .PA file, create a .7z file instead.
You’ll notice that both the large and small archive is created without any issues.

hey, i dont think it has anything to do with admin rights, rather issue is 32bit OS and too much memory needed that PA at 32bit can not address.
Can you tell us what settings for compression are you using? We have many limits on 32bit systems but we maybe did not get it right.
thanks!

but generally, lower down your thread count and compression strenght… @Mili will check if somehow on protable version we have this issue where we dont lower it automatically.
-
initial test showed no error, but we are still testing. Could you let us know what settings you used when compressing to PA? We’d like to test with those exact settings.
Thanks! -
Method: Optimize Strong
Compression: Extreme
Threads: 2 (Automatic = UNCHECKED)
Add to queue: UNCHECKED
Low priority: UNCHECKEDI shouldn’t have to lower compression settings.
PowerArchiver should adjust to the memory I have available.
