dired-filename-display-length is a customizable variable defined in dired.el.gz.

Value

nil

Documentation

If non-nil, restrict the display length of filenames.

If the value is the symbol window, the right edge of current window is used as the restriction. Otherwise, it should be an integer representing the maximum filename length.

The middle part of filename whose length exceeds the restriction is hidden by using the invisible property and an ellipsis is displayed instead.

This variable was added, or its default value changed, in Emacs 30.1.

Probably introduced at or before Emacs version 30.1.
