Right now, JuliaHub’s DataSets are a fairly thin layer atop the native cloud blob store (an S3 bucket in this case). So they’re fetched on-demand and don’t actually ever appear on the filesystem unless you explicitly download them.
So we don’t (yet!) have the ability to show them in the filesystem alongside your code. But we’re actively building a more seamless filesystem integration, and hopefully it’ll be easier to use in the future!
