Necessity is the mother of invention

"Difficult situations inspire ingenious solutions."
I had already written several separate files and then I wanted to change a word that was frequently repeated in most of the files. This necessity prompted me to investigate whether there was a software that could do it - et voilà!  This software existed: "Word Batch Replacer". Simple to use and effective! My problem was solved. Thank you, developers, for having thought about this necessity!
