I have a problem while deploying a new Big Object to my developer ORG from my windows machine. I was doing the exact steps mentioned in Trailhead and deploying the big object using Workbench. I have created the objects and permissionsets folder and put the object file and permissionset file respectively and created the package file on the root directory, then i make a zip folder of the folders and that zip folder was selected as the source file of workbench and selected the options Check only and Single package. Then going further i got this error message No package.xml found
It would be a great helpful to share what went wrong.
