Application Octet Stream File
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.
Octet-stream files are usually executable application files. If still having trouble opening a file, request that the sender attempt to retransmit the file. Email or web clients are rarely able to open octet stream files, but may be able to determine the appropriate program to open the file. These OCTET-STREAM files may be opened by renaming the extension of the attached file to a specific file extension, and then by using an application with support for opening such files. For example, an.octet-stream file may be renamed to a.txt file (if it is indeed a.txt file), and Notepad may then be used to open the file.
Application/octet-stream File Type
No matter what kind of file it is, an application/octet-stream attachment is rarely viewable in an email or web client. If you are using a workstation-based client, such as Thunderbird or Outlook, the application should be able to extract and download the attachment automatically. After downloading an attachment through any of these methods, you must then open the attachment in the appropriate application to view its contents.
The content-type should be whatever it is known to be, if you know it. Application/octet-stream is defined as 'arbitrary binary data' in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything 'webby'. Application/octet-stream This is the default for binary files. As it means unknown binary file, browsers usually don't execute it, or even ask if it should be executed. They treat it as if the Content-Disposition header was set to attachment, and propose a 'Save As' dialog. The OCTET-STREAM format was developed for Web browsers to understand that the file attachment is in an unknown file type, which also allows the user to choose to download and save the attached file in any file format that the user wants.In other instances, the OCTET-STREAM file format is used to inform the user that the attached file may be saved in a recommended file format.
Start MetaEdit, open the LM tree in the left hand pane, and then open the MimeMap folder. In the right pane, double-click ID 6015 MimeMap. In the Data list box, scroll down (about half way) until you find.,application/octet-stream. Change the value to.,text/html.
Before opening attachments, even from trusted senders, you should follow the guidelines listed in Tips for staying safe online. /download-torrent-hindi-audio-songs-new.html.
Application/octet-stream Files
In addition to the generic application/octet-stream content type, you may also encounter attachments that have different subtypes (for example, application/postscript, application/x-macbinary, and application-msword). They are similar to application/octet-stream, but apply to specific kinds of files.
