how to Find/Replace multiple lines in Notepad++ within a FOLDER?

Question

is there any plugins for notepad++ existed to replace multiple lines within a FOLDER? (not a single file).

Answer 1

If you mean you need to replace texts in multiple files inside a folder, then you may use Replace in Files.

Press Ctrl+H > Find in Files tab -> set the options as needed and click Replace in Files button.

If you check In all subfolders, all files in the subfolders that match the selected mask will be processed recursively.
