When I upload files from Users OneDrive Account to a Teams Channel from within the Teams Desktop App, am I, a) uploading a copy or b) effectively uploading a shared link (permission defined permitting).
From my knowledge, there is a Move option in Teams where you can move files to a channel directly in the Teams client. When you move files to a channel, Teams channel files are saved in SharePoint. In both places you can set access permissions, and changes are synchronized automatically.
