Dear Developer Team,
File Upload via Zip File is not working getting on this file “modules/System%20Admin/file_uploadProcess.php”
Hmm, this is odd. Can you check your System Admin > System Check page to see that the zip extension is installed, and also PHP error logs to see what the exact error is. It could be that the file size exceeded your PHP upload_max_filesize or post_max_size, depending on your settings in the System Check.
