It was necessary to change the text in the directory containing the .html, .htm files. To be more precise, change the links in HTML documents. The number of .html, .htm files could not count 200 or maybe 300. A directory tree can be up to 5 levels.
Can you please tell who knows how to rename links in .html, .htm files not manually?
For example, replace http://domain.com.ua/
with http://newdomain.ru/
