A zip file is a type of archive used for storing and distributing files. It can contain one or more files and folders. This is usually used to reduce the size of the file. However, it is also used in the case of file grouping. For example, you want to provide a project example of your visual basics online that users can download at will. Now if you want to give the option to download the files used in your project (I assume 8 files have been used in your project) separately, then you have to instruct the user to download the project six times. However, if you compressed the whole project into a zip file, on the one hand the user could download the project with a single download instruction and on the other hand the download time of the project would be reduced due to the reduction in file size due to compression.
