More channels or more sub-folders?

[Amended answer, previously read it wrong :D]

Thanks for submitting your question!

I thought about this a bit - I could give you an 'it depends' answer insofar that it depends what you are trying to achieve. However, from experience I find that separate channels wins out and has more advantages. This is not really because of the files - it because of what Teams is and that files is only one facet/aspect of teamworking. When doing projects or workstreams, you have conversations around those, you have apps associated with those, you have calls around those.  By definition, Microsoft defines channels as dedicated sections within a team to keep conversations [and files, apps etc] organized by specific topics, projects, disciplines. Typically, working out of the singular general channel muddies the water when trying to use different applications or when conversations merge into one within the posts tab of the general channel. Organisations quickly pick up on this then typically want to split everything out. 

So I would absolutely go with separate channels on this one.
