For Gerber files (PCB) you need to have all the files in zip file. For example if you have a Mac and when you download Gerber files, your Mac will automatically unzip all the files into the folder and will place it into downloads folder. You must compress those file back into 1 zip file, otherwise PCB printing Company will not accept it.
