How to count Folder's words or characters?

I know how to count Text’s words,
but I have to know my Folder’s words count,
any body know how to do that?

English is not my mother tongue, please try to read my words.

Thanks!

View > Editor Layout > Show Footer View will display a footer at the bottom of the editor window.

If you type in a folder or text file, the word count should be shown in the footer.

Does this do what you want?

You can also enable the Total Words column in Outline view. (View -> Outliner Options) – Katherine

Thank you!

Thanks!
