Hello everybody, My desktop runs Windows 10 Pro, build 1803. I schedule
regularly an application that creates log files; I chose to name them
xxx.log.

The default application to read log files is Bloc-Notes (I have a french
Windows, the english version may name Bloc-notes differently). If I am
not mistaken, the underlying programme is notepad.exe (but this is
irrelevant to my problem). Bloc-notes seems to have problems
understanding carriage-return/new-line and the log file is shown on the
screen as a very long string of characters. WordPad.exe on the other
hand shows the file contents as a line per log entry.

Both right-click-"open with" or right-click-properties give you the
choice of opening the file with Bloc-notes or WordPad; WordPad is my
preferred "open with" application. However there is no way of
associating WordPad with .log files. Even though I choose WordPad as the
preferred application, Bloc-notes comes back the next time I open the file.

Even the list of file extensions and associated applications in the
Windows-Parameters menu matches .log files to Bloc-notes and refuses to
accept WordPad as the preferred application.

Any help to have it my way instead of Mr. Gates' will be appreciated!

All the best, Matitico

I recommend you get notepad++ instead and associate that with your log
files. The default notepad.exe (called Notepad in english) is useless.
