The Replace in Files feature is a feature of EmEditor Professional. Just like the Find in Files feature, you can use regular expressions to search for specific words and characters. You can also specify an encoding to use for the document. To prevent unwanted automated editing, such as inserting unintended words, EmEditor replaces the words you specify, but leaves the editor open without saving changes right away. Replaced words are highlighted to assist in confirming your changes. If you do not wish to keep the changes, they can easily be removed with the Undo command.
