Assigning this to myself so I can filter for it :-) Also related to #33.

Doing some end-of-project cleanup. I think we never got around to doing this one, although it would be useful. @lozanaross I feel inclined to unassign this issue from you and generalize its description so that someone else can get to it at a later point (both design and development-wise). Agreed?

It's probably also relevant for Wikibase uploads, as duplicate file names are not allowed there either?

Yes, all fine to generalize issue. I have some ideas related to upload process and error logging that I'll try to do a final design on as part of the report wrap-up of the final user testing sessions, but that won't be something necessary to be built or finalized in the short term.
