I exported my gerber files to a zip file NO sub directories and when I try to upload the file it says a sub directory was detected. If I try uploading the individual gerber files it says its an unsupported file type. I have 8 Files 1 txt 1 drill and the rest gerber files. Am I doing something wrong?
Open your zip file and check to make sure there are not any folders or directories inside. If there are none, email support at batchpcb.com with the submitted zip file and we will have a look at it.
