How to add "edoc" file type in Plupload

Question

Does somebody know how to add the file type "edoc" to Plupload?

I'm trying to do it in two ways, but nothing successful.

Both ways not working:

filters: [
            { title: "Documents", extensions: "docx,doc,xls,xlsx,pdf,edoc" }
        ],

and using mime_types

filters: {
            mime_types: [
                { title: "Documents", extensions: "docx,doc,xls,xlsx,pdf,edoc" },
            ]
        }
