FINDSTR search for a couble quote and redirect/pipe the ou..

I cannot get FINDSTR to search for a string that contains a double quote and
redirect its output. It seems to get confused with the double quote. It
works fine and will alaways return its answers to the screen but I cannot
redirect any search looking for a double quote. I can redirect any other
searches though. Below are some examples


This works (searching for ." ):
findstr /S /I /M /C:"\.\"" *

This does not work (same search, just redirect output):
findstr /S /I /M /C:"\.\"" * > x.txt

This works (search for dbo and redirect output to z.txt):
findstr /S /I /M /C:"dbo" * > z.txt
