hello and welcome to the notepad++ community.

usually you have to unzip your file locally,
change the template files to your needs using notepad++,
and then upload the extracted files uncompressed to your web server using external ftp progrms like filezilla or the notepad++ NppFTP plugin.
(you can install NppFTP plugin in notepad++ by using the menu
plugins > plugins admin and search for ftp)

Notepad++ is a text editor…which means it can do text editing. Not sure how what you’re asking falls into that category.
