I knew the type of nodemcu2.svg file.
Formerly my PC configuration files opened. svg with Internet Explorer and that is the reason for network access.
I then tried to install INKSCAPE in order to open the files with this nodemcu2.svg TOOL.
Unfortunately the result is negative, it opens a blank window as before
Which tools I need to link to the file in order to display properly nodemcu2.svg ?
Thanks a lot
