Wikimedia Commons deals with large files in a variety of ways; see https://commons.wikimedia.org/wiki/Commons:Maximum_file_size for some context and pointers.

Some end users of Wikimedia Commons batch upload tools have pointed out that they want to upload batches of larger files (e.g. book scans, video files), where individual files can be 1 to 3 GB or more in size. Such large file sizes are currently not handled very well or straightforwardly in existing upload tools like UploadWizard or Pattypan.
It would be desirable if OpenRefine would handle these better, and/or at least communicate clearly which issues exist around such files during upload.
