Just wanted to share my .BAT file for generating .ZIP file for oshpark.com / ITead Studio / etc services.
Download and place it inside "Project Outputs for ___" inside Altium project folder.
Double click and it will copy necessary files and compress them with WinRAR into a .ZIP file and add archive comment from "Status Report.Txt".
After .ZIP is all done, temporary files are deleted.
I use it to quickly check design on OSHPark as it can sometimes reveal things I miss otherwise.
