Learn how to share a file from your SharePoint site with anyone including people from outside of your organisation. Use the edit settings, link expiry and download blocking to control what people can do with your file once you have shared it with them.
The files on your OneDrive are private until you share them. Keep in mind that when you share folders with Edit permissions, people you share with can add the shared folders to their own OneDrive. This lets them keep the folder alongside their own folders and items, easily move items between folders, and more easily work on it offline.
In a Microsoft SharePoint document library, create a new file, upload your own, and then share it with others.
