I, too, would like to know where I can find the list of default file types/mime types that I can upload to my WordPress site. I tried to upload a WAV file and although I did not get an unsupported error (it was more of a server is busy kind of error), I have not been able to upload the file.
I am interested in the default list, not the list or plug-in tha allows me to ADD specific types to the list.
