notepad++

I would use TextPad.

Can you explain some of the "filters" a bit more?
Gracie has a great suggestion. I use  http://TextPad.com daily for the last 10 years,

Please, the more you input the more we can correctly and efficiently output.

The NOtepad++ filters are just wild card characters.   Maybe my use of the word filter is misleading.   I  want to be able to make a set of repetitive text changes to a set of specific files within a folder.  

I'll look at TextPad.

In TextPad, how do I do this?  I see where I can do a Find of text and select the files I want and save that as default.   But after the find, how do I do the replace? The files are not opened.

I can also do a Replace, but that requires the files be open in Textpad.

I think I understand. Is it search and replace you are looking to do?  
Or you need to locate files with specific words and replace the words in them
with out opening them?    
Why not use a program like 12 ghosts replace?

Are all the file you are editing in the same folder?
Do they have the same extensions?

Can you give any examples of what you need to do exactly.
