Sharpoint Connection

For my job, we want ot create a sharepoint that other departments, and outside people have access to. We want to be able to have content (recorded videos, PDF flyers, and other resources) available for all the other stakeholders to access. We have a few teams that have that different resources in them, one for PD, one for our whole team, and its not all consolidated and our team does not want to consolidate them. 

Is there a way that I can upload the information to a sharepoint without having to individually upload the content one file at a time, or if there was a way to link them together?
