Form now on + we won’t - Is this correct usage?

[Sureshvemuri]

"Form now on, we won’t add folders without your knowledge. I had those files("A","B") removed from "MY Folder" folder."
Are the above sentences correct?

Q: "Shall I do?"
If the person is not supposed to do the above task, my answer should be:
ANSWER: "No, you shall not"

Is this correct.

For every small clarification, do I need to open a new Thread, or shall I include the new one in the old Thread.

Thanks, Suresh
