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
Maximum number of files in a ZIP archive
-
According to the PKWARE website, the maximum number of files in a ZIP archive is 262,144. How is it possible that PowerArchiver supports an “unlimited number of files” in a ZIP archive? Is PowerArchiver using a different ZIP format? Or is PKWARE wrong here?

PA uses an advanced ZIP format ZIp64 as far as I know

PA uses an advanced ZIP format ZIp64 as far as I know
So PKZIP doesn’t use that format? Does that mean that PKZIP doesn’t understand PowerArchiver’s ZIP file format?

Hi,
you are correct - limit is 262,144 files per archive, everyone writes “Unlimited” or virtually unlimited because it is considered to be hard to reach. Same goes to archive file size, which is not unlimited either but it is more than a terabyte.
PowerArchiver fully supports PkWare’s 4.5 standard, so it supports whatever that standard supports. I have to say that I wasnt even aware of actual number itself, and PkWare usually writes “virtually unlimited” in the press releases, same as WinZip.
PkWare original press release stated:
ZIP Format Enhancements Virtually Eliminate Limitations on Archive Size and Number of Files (in an Archive)
We probably should change it on our feature page to show the actual number of files supported. Thanks for pointing it out.
