The Zip List reader step is added to unzip the file that is retrieved from the server as shown in the below image.
NB: Please note that this step only works for a zip extension.
The below page shows the output from the Zip List reader step that lists the files from the zip file.
In the MySQL destination step, an Upsert is done to check if the file name exists and to save any new file name in the table.
