Yes stored in Sharepoint, however stored in the name of the folder used in Teams groups.
If I have a team called Board, and a channel called meetings, files used here will be saved in that folder when opening Windows explorer.
However using just Word, its saved in Board-Documents.
For me, its saved in different location, regarding if using Teams og Sharepoint.
Document A has until now been saved and edited using Word.
After started using Teams, document A has been copied to Teams channel.
Ducument B has some links to document A - these links has to bee copied from the Board-Teams-documents.
If we the create a new channel, called project. In that very same channel Document A is used. Document B would then have som links til Document A (Board - Teams-Documents). These would not be updated, as Document B now is saved in a different folder (Project-Documents).
Now:
Team called Board. Document A and B saved in Board-Documents-Projects
New team called Project. Document B has been moved here.
Document A has links til Document B - ok, but after moved to new team, these links would need to be updated.
Hope this made some point in understanding.
