I need to upload some audio files in order to use them in some questions. I have them in a zip file and when it finally uploads an error message appears saying there's no valid survey archives.
My file doesn't have sub-files and I'm trying to upload .wav audio files so I don't know what to do. Also I tried uploading the files from internet explorer and from firefox and the results were the same
Is there something I'm missing that could explain this?
