Currently, we have uploaded a lot of data in Teams via files on SharePoint Site. However, these are unmanaged and scattered across. We are trying to separate Teams and SharePoint Doc library, so that it is easier for us to manage data files and folders uploaded in Teams. Is this a doable task, and please let us know how?
Teams channel and SharePoint folder cannot be unlinked.
Could you elaborate a little bit more what you are trying to achieve here?
If you just need to move files and folders from that channel linked folder, you can create a new folder on SharePoint Document library and move files there using SharePoint out of the box functionality.
