I am a computer programmer. When I create a text file and change its extension to .py, for example, the following window pops up:

It annoys me very much to constantly confirm
Tell me how to remove this window

No way.
But who prevents to create a file at once with the necessary name.
Or use another file manager to rename the file, which does not ask such questions, since they annoy you so much - headlights, total commander, and others ...

There is a "show extensions" option in explorer settings.
