Thank you so much Greg! 

The original question was that if the file is say
"Atest.txt" then I want copy it to 


and I got it by tweaking your script!

Copy them where?

You want to copy each file to a new file in the *same directory* with
_new inserted before .txt?

find . -type f -name '*.txt' -exec sh -c '
  for f; do cp "$f" "${f%.txt}_new.txt"; done

' x {} +

Purists will insist that I remove the ; after "for f".  Decide how pure
you wish to be.

You have at least two fundamental mistakes in yours:

1) Unquoted *.txt glob expands to files in $PWD instead of letting find
   expand it.

2) You pipe find's output to a loop that does not read it, and which
   then merrily proceeds to do its own *second* nonrecursive glob
