Par file problem

Your error message says: "Either this file is not a zipfile, or it constitutes one disk of a multi-part archive."

It sounds like you are using unzip to try to access the ".par" file. That won't work. Unzip is for zip files, not Parchive Version 1.0 files.

You need to use a program that understands the Parchive Version 1.0 file specification. But, if you are not familiar, Parchive Version 1.0 is used to repair damaged files; it does not contain the original files. You only need a program that understands Parchive Version 1.0 if the original files are damaged.

Par file problem

We have a .par file that was written by someone who no longer works at our company. All of the machines we are using are running Fedora 34. On some machines it works fine, but on others we get the following error. We have tried multiple times to copy the same file from a working system to a non-working system, but the issue always follows the system. Any help or suggestions would be greatly appreciated.

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
note: ./vrs2png.par may be a plain executable, not an archive

The slightly older version from https://github.com/Parchive/par2cmdline/releases/tag/v0.8.0
seems to work little more efficient and even a bit faster. Better still use this older build.

Maybe worth a try, does threading and uses up all cores on modern CPUs.
The code did compile in VisualStudio 2019 for 64-bit windows cmdline exe.
