You can download any file you see in Teams—whether it’s in a channel’s Files tab, sent in a message, or stored in a OneDrive folder. Select More options next to a file name to see the options for downloading it, opening it, or getting a link to it.
Files and images downloaded from Teams will show up in your devices Downloads folder. Currently, there is no setting to change the download location.
Selecting Files on the left side of the app lets you view recently accessed files, a list of your files in Teams, OneDrive and other cloud storage files you’ve added to Teams, and your download history.
Note: The downloads list clears each time you log out of Teams.
Use the desktop or web app to download files.
