I had a case where an overlong file path was calculated as 200 chars, although it was over 260 chars long. (I temporarily displayed a column showing the path length.)
Thus, it was not colored according to the coloring rule.
It was a pdf file with multiple dashes, dots, underscores, and spaces in its name.
But for all other files in the same folder, the file path length was calculated correctly, as it seemed.
If you know of any way, Mathias, how to make the file path calculation more reliable, please do so. Many thanks in advance.
