The pack consists of the main folder named as source code. Inside the folder, there are further files that would show up like this.
Both of these folders i.e adminpanel.zip and api.zip are respectively for admin panel and mobile application api.
AppSourceCode.zip contains full source code on ionic application.
Updates folder consists adminpanel and api updates. If you have already setup adminpanel then you can install updates instead of new installation i.e if you have version 4.0.5 and we have released next version 4.0.6 then you can go to adminpanel>Managements/Update Project/ and upload admin and api zip files. So, with this updater feature you can update adminpanel with single click and without losing any data entry 🙂
