Unknown file type MIME?

Do I have to specify a MIME type if the uploaded file has no extension? In other words is there a default general MIME type?

Solution

  • You can use application/octet-stream for unknown types.

    RFC 2046 states in section 4.5.1:

    The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data.
