Before installing the application to the site controller, what must be done with the overlay.zip file?

For the installation of an application on the site controller, it is necessary to unzip the overlay.zip file prior to the installation process. The purpose of unzipping is to extract the contents of the compressed file, which typically includes the necessary application files and directories needed for installation. Without unzipping, the system would attempt to read the compressed file, which would not contain the unprocessed files required for installation.

Unzipping ensures that all files are accessible in their appropriate formats, facilitating a smoother and more effective installation process. This step is crucial because the installation routine usually looks for specific file types and structures, which are only present once the files are extracted. Other options such as renaming, compressing, or simply copying the file do not facilitate the preparation of the application files for direct installation, making them unnecessary steps in this context.
