Question : Edit multiple .txt documents via a batch program

I have 1000+ .txt files all saved in multiple sub directories. I need to modify these .txt files to remove out any # and replace it with a *.

Is there a good batch program that will not cost Big Bucks that I'll be able to select one master folder and have it search each sub directory for all documents, changing the # to * in each file?

Thanks

Get chgstr.exe from http://www.paulslore.com/index.php?option=com_content&task=view&id=49&Itemid=46, and apply it like this:

chgstr "#" "*" c:\targetfolder\*.txt /d /s
