Find and rename files with no extension?

Question

So, I\'ve got a bunch of files with no extension. I want to write a windows batch script that will:

1. Find files with no extension (in a specified folder)

Answer 1

to do this in subdirectories use this:

 for /f %a in ('dir /b /ad /s') do rename %a\*. *.bla

if you are using this in a batch file, you need to double the '%'

 for /f %%a in ('dir /b /ad /s') do rename %%a\*. *.bla

edit:

and if you have spaces in your directory names, you can try this (batch version):

 for /f "tokens=* delims= " %%a in ('dir /b /ad /s') do rename "%%a\*." "*.bla"
