Questions about example sentences with, and the definition and usage of "Forwarding"

A: If used when talking about an email, it’s like when you copy a email you got, and send the same email to someone else to see too.
“I’m forwarding you the email now”
“I’m sending you this email that I got so you can see it too”
The two sentences above are pretty much the same, forwarding just means you already got the email, and you’re sending it to someone else to see.

A: 'I'm forwarding' means you're sharing some kind of source you have to somebody else. You're gonna 'forward/share' the text/video/etc to them. I don't know if this is the correct context you mean though.
