It's very simple really. There are Drives and Sites. You can find your Sites in Teams where they are called Channels. Or Files in Channels. Sites are also in SharePoint. Drives are also in SharePoint but you can't access them that way except by accident. Libraries are Groups that are also Files (but Teams calls these Knowledge Bases). You can save things in Notebooks which are saved in a Drive but can also contain Drives or Sites (but not Teams, which are what Teams calls Teams and where Channels are stored, which SharePoint and OneDrive call Sites). Copilot is both a way to access Sites and Drives, and a way to produce lies. Nobody knows what 365 means. If all of this is overwhelming, consider speaking to your administrator about whether Microsoft Death is right for you.
