  1. Great guide..! I have the following question:

    “..EditPlus supports following regular expressions in Find, Replace and Find in Files command..”

    Can we use ‘Replace” command for multiple files within a folder structure, as in ‘Find in Files’, or is it limited ONLY to finding files? Trying to see if I can do this with EditPlus or should I code a script in Perl.
