"what is mean by "binary ", where we can change it
Unless the group name has the word BINARY in it, it means that it's a
text only group - which means you don't post FILES to it. Most Usenet
groups are text only, a few are HTML and there are a number of ALT....
groups that support Binary attachment posting.
Since you're using Outlook, you need to know that Usenet is not like
email, you don't use it the same way. You message is not private, it's
sent around the world and appears on other Usenet servers for everyone
to see. It's part of the standards to NOT post files or attachments to
non-binary groups.
