Binary
Content-Type: "application/octet-stream"
A MIME attachment with the content type
"application/octet-stream" is a binary file. Typically, it will be an application or a document that must be opened in an application, such as a spreadsheet or word processor. If the attachment has a filename extension associated with it, you may be able to tell what kind of file it is. A .exe extension, for example, indicates it is a Windows or DOS program (executable), while a file ending in .doc is probably meant to be opened in Microsoft Word.No matter what kind of file it is, an application/octet-stream attachment is rarely viewable in web client. After downloading an attachment users must then open the attachment in the appropriate application to view its contents.
