Learn how to find and filter your files in this Microsoft Teams tutorial. In Teams select "Files" on the left menu bar to access your documents and files. To view your most recently created or edited documents, select "Recent". If you would like to view your most recently downloaded files from Teams, select "Downloads". If you have files saved on OneDrive, Teams is automatically connected by default and you can access them within Teams. If you are using another cloud storage provider, you may add them by clicking "Add cloud storage" at the bottom of the left rail.
