.pak files

After installing Bootstrap Studio, a series of files appear in the folder "locales" with the extension ".pak". They seem to be translations to different languages. Do any of you know what they are for and how they are used? Thank you very much for the information

Hello, I'm actually interested in this too. Anyway, I would have generally the question if the surface can be translated into another language. At least I would assume, based on the files in the "locale" folder, that there must be a translation for different languages somehow ...
