● Firstly, Open the Zip Extractor Pro and double click the already existing archives.
● Secondly, click "Add" drop the new content into it or right-click and choose files. click "OK"
If items with same name are detected inside the current archive the application will prompt a warning to confirm overwriting pre-existing data.
