Try running this on the commandline
file --mime-type -b myfile.zip
Does it output jar ?

Why is my ZIP file being viewed as a JAR file?
I have a store endpoint, that only allows files of type 'zip'. This is my validation statement:
"file" => ["required", "file", "mimes:zip"],
When I upload a zip file, this validation statement returns an error: "The file must be a file of type: zip."
When I remove mimes validation, it gets saved to the server, with an extension of ".jar". Can anybody share some insight, please?

@Sinnbeck I transferred the file manually, via FTP. It has the zip extension, but the command outputs "application/java-archive"

@ivymasterman Then it is a java archive :) Linux uses the mimetype to determine the type of the file.
You can perhaps allow that as well, and just manually set the filename when saving it https://laravel.com/docs/9.x/validation#rule-mimetypes

Jar, is a JavaArchive and that is basically just a zipped bunch of java files.
Java ARchive This format is a Java archive and is presented as a typical ZIP file, in which part of the program is written in Java language. It was gradually replaced by new mobile platforms, since JAR is used for launching applications and games on early generation mobile phones. They can contain a digital signature, and they’re actively used in popular browsers for storing supplements. - https://convertio.co/zip-jar/
