Teams is a Microsoft product so files are stored on the same Microsoft servers as OneDrive and SharePoint.
Where do I find the files?
Each channel has its own area for keeping files, separate from the other channels. Open a channel and select the Files tab at the top. [see screenshot] To create new files, click New in the top menu and select the file type. To upload, click Upload at the top menu or drag and drop the file from your computer.
When in the Posts tab within a channel, you can attach a file to a conversation using the paperclip icon [see screenshot] or drag and drop the file into the message. This will also upload the attached file to the Files tab in that channel.
Your Microsoft Team also comes with a Team Site in SharePoint. All files back-up to the document library found on that Team Site which you can access by clicking Open in Sharepoint in the Files tab. [see screenshot]
Each channel will be assigned its own folder in SharePoint.
- If you change the name of the Teams channel, it will not automatically change the name of the folder in SharePoint.
- All files uploaded or created in Teams will show in the SharePoint document library, but not from SharePoint to Teams. Although you can create files in this SharePoint library, you will not be able to access them from your team files. It is a best practice to create and upload everything from your team file tab.
Private channel back-up
When a private channel is created, a new, abbreviated SharePoint site is created just for this channel. This ensures any files created in the private channel can only be accessed by those who are are owners/members/guests of that channel. The channel will have the same name as the team with Private channel added to the end of the name. For example, if your team name is Project Q, the private channel will be called Project Q - Private channel.
