@dougevans. Ok, let me see if I can explain a bit better. The idea of the test script is to find out what functions work with your server, and to see what mime types they detect on your system. So, if you plan on uploading only pdfs and word files, then what you do is ftp to your site and place a pdf file, a doc file and a docx file, and the test script file in a folder, and then run the test script. That will tell you exactly what is being detected. Then you will know exactly what mime types to specify in the “Permitted file types” in the Module Manager.
I hope that clarifies how to best use the test script.
