      description: |
        Replace the contents of an existing file. The workflow to replace a file is as follows:
          1. Set isUploaded flag to false
          2. Replace contents of the file in the storage backend
          3. Update file metadata (size, mime-type, isUploaded, etc)

        Each individual state is atomic but if a step fails, previous steps won't be undone
