DOS Command FindStr

I have a need to use the DOS command FINDSTR to search in all our source code files mixed with other types 开发者_如何学Pythonof files such as PDF, exe, dll, etc.

I do not need to search those binary files. Is there a way to exclude binary files?

My command looks like

findstr /r /n /o /s /g:c:\projects\vsssearch\muafinddata.txt /d:c:/projects/axl *.axl > output.txt

Thanks in advance for any insight.
