 ### Zipped Artifact Downloads
 
-During a workflow run, files are uploaded and downloaded indivdually using the `upload-artifact` and `download-artifact` actions. However, when a workflow run finishes and an artifact is downloaded from either the UI or through the [download api](https://developer.github.com/v3/actions/artifacts/#download-an-artifact), a zip is dynamically created with all the file contents that were uploaded. There is currently no way to download artifacts after a workflow run finishes in a format other than a zip or to download artifact contents individually. One of the consequences of this limitation is that if a zip is uploaded during a workflow run and then downloaded from the UI, there will be a double zip created.
