Anyone Know difference between pure Text Document and Plain Text Document?

I am having a **** of a time trying to figure out how to create a "text document" on the Mac. From what I've read, it's not possible to create a pure "text document" with Mac .... only possibly windows.

I have a text document (created in Textedit in Mac),that can only be saved as either a "plain text document" or a "rich text format (.RTF) formatted file.
I need to save (or re-create), the text file in a file that will save as a
"text document".

In either the <command+I> option, or in a folder window line description, I need to see the text file saved as the wording or a "rich text format (.RTF) .... and not "plain text document" or a "rich text format (.RTF).

Evidently, the difference between the text files that Apple TextEdit creates, and those that are a pure "text document", have something to do with the hidden carriage return command language at the end of the command lines ... or something like that.

The text file is being used as a command text file for a modified VTC Training "set-up folder/GUI" that will run on either Mac or Windows.

I have seen on-line, some mention that using windows "notepad" (texteditor) may be the only way to create a true "text document" labeled file.

Any suggestions, or knowledge in this area would be greatly appreciated.

Thanks! -David
