Where to put files in Lilypond 2.24 ??

[eltnap]

I can't find the font-folder containing with its sub-folders called "otf" and "svg"

any help ?

Very late reply, but they can be found in:

<installation-folder>/share/lilypond/2.24.<n>/fonts

...where <installation-folder> is where you installed LilyPond on your system (e.g. lilypond-2.24.3) and <n> is the minor version level (e.g. "3" in this case). In Windows the slashes are backslashes (\).
