InsightsHub ZIP import tool is similar to the files repository, but it creates one Project per file uploaded. This may or may not be what your team needs when importing files into InsightsHub. For example, if you have several files that belong to one insights project, you probably don’t want a separate project created for each one of those files. But if you have one file per project, ZIP import is the way to go.
To access ZIP import, go to Settings >> Setup. Scroll to the bottom — ZIP import is listed alongside other integrations.
