Application/octet-stream file extension

When we go back on-line we can either upload the the information from the application or we can upload the backup files. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.

Typically, each byte is an 8-bit quantity octets , and so the term octet stream is sometimes used interchangeably. Octet-stream does not refer to a specific type of file - it could be anything from a spreadsheet to an executable program. To open an unidentified file, you need to either figure out which program can open the file as a document or change the file's extension to run as a program.

RFC also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter.

This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not as the suggestion if the user tries to save. Means "I don't know what the hell this is. Please save it as a file, preferably named picture. Means "This is a PNG image. Please display it unless you don't know how to display PNG images.

Otherwise, or if the user chooses to save it, we recommend the name picture. Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing or at least IE used to be like that, it may have changed some years ago.
