how do I remove these messages from AFR

[kleino]

I get these messages when running afr


I dont understand them. I dont want to re[place the file. I am simply replacing text string INSIDE the file.

How do I get rid of the messages? How do I get the program to keep going and not stop?

where are the regular expressions modifiers explained?

Go to menu Action - Options - Batch Replace
uncheck the option: "Replace in File Names"
