Ideally when you download a package the file name would be Data project name instead of the current {97A09CE4-413A-41BE-9612-82165FE06E99}.zip name. You have to re-name the files so you know which ones you're working with or take a gamble on you're working on the right one when loading the package into another environment.

This is done from the main data management workspaces and job history. Clicking on Download package.
