Regular Expressions
Search/Replace/Find in Files/Replace in Files and Replace All
In EmEditor, Find and Replace features are available with Regular Expressions supporting Unicode. Regular Expressions find text patterns within an open document or in multiple files. When using Regular Expressions, select the Find (to find text patterns in the current file), Replace (to find text patterns and replace them), Find in Files (to find text patterns in multiple files) or Replace in Files option (to find text patterns in multiple files and replace them) under the Search menu. Then check the Use Regular Expressions check box, and any other desired search parameters. Enter the Regular Expression to search for, and click Find. If using Find in Files or Replace in Files, also enter the file type(s) (separated with a semicolon if more than one) and the folder(s) to search. If using Replace or Replace in Files, also enter the text to replace the found text pattern with.

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, you can easily remove them with the Undo command.
EmEditor includes an optimized Replace All feature. In normal search mode, the replacing feature slows down significantly because of the file size. However, if you select the check box next to "accelerate by discarding undo information" the search executes much faster because it discards the undo information immediately rather than saving it for review.
