In rare cases, you can try to unzip the zip archive and encounter an error that says “The signature of the end of the central catalog was not found. Either this file is not a zip-file, or it is a single disk from a multiple-part archive. In the latter case, the central directory and zipfile comment will be found on the last disk (s) of this archive. ” This guide will attempt to eliminate the errors of the zip file “End of the signature of the central directory was not found” when trying to unpack the archive.
To make a backup, the reason why you usually see the “Not found signature end of the central directory” error when working with a zip file is that the file is damaged, the file loading is incomplete, or it consists of several parts. The archive file and other components were not found, or the zip file is not in fact a zip archive file. The most likely reason why most users encounter this error when trying to unpack a zip archive is that the download of the zip file is either not completed or the zip archive is corrupted.

To extract the target zip archive, try another unzip program, for example, “unzip” on the command line, Unarchiver for Mac, jar, 7z, rar, gunzip, etc.

I recently encountered this problem several times when trying to set up a Signal messenger on a Mac, but I was eventually able to solve it by downloading Signal using curl instead of (admittedly outdated) web browser, which is a bit curious, but decided anyway. Using a different download method also often helps fix the unpacking loops of the CPGZ zip files and usually assumes that the file was damaged for one reason or another.
