Problem with "Extract All" when downloaded files are in multiple parts

I have downloaded a file in multiple parts such as this:
xx.part1.rar
xx.part2.rar
When I run "Extract All" I get this message:


Obviously, it needs to be able to handle multi-part downloaded files.
FYI: I can extract the content using 7-Zip, I don't use WinRar due to it's security vulnerabilities.

Windows 11 has only just got support for extracting archive formats other than a .zip file. Windows has supported the zip format since at least Windows 7.

The support is fairly basic, and does not support multi-part archives of any format, not even .zip. In addition, you cannot set a password for any archive you make, and can only extract a password protected archive that's a zip archive. Explorer only supports extracting simple archives, you'll need to keep using 7-Zip for anything more complex. It is unlikely MS will add any new functions, after all, they haven't done so for zip files in all the years they have supported them.

Usually the need for 2 or more parts of a compressed file is due to it being too large for a single file. WinRar probably will be needed to put the parts together then extract the files.

Both WinRar and 7-Zip support making or extracting muti-part archive files. They are less common these days, but were widely used back when archives had to fit on multiple floppy disks. They are less common now, but can be still found when downloading older software, archived when the practice was more common.

Windows File Explorer does not support extracting multi-part archives, and it's unlikely it ever will. For that WinRar of 7-Zip will be required.

You need to download Win RAR to Extract Multiple RAR files.

7-Zip just did some multi part RAR files for me this morning. It does work, and it's free. The files came out perfectly.
