Including file in .cls

Question

I have created a class and defined a command in there, to create a titlepage:

class.cls :

\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myclass}[2019/03/25 myLaTeX class]

\LoadClass{scrartcl}

\RequirePackage{etoolbox}
\RequirePackage{babel}

\edef\file@titlepage{titlepage-\languagename}

\renewcommand{\titlepage}{%

\makeatletter

\input{\file@titlepage.def}

\raggedright

\pagebreak
}

Now I am calling \titlepage in the .tex file:

\documentclass[english]{myclass}

\begin{document}
    \titlepage
\end{document}

My texmf directory looks like that:

• C:\localtexmf\tex\latex\myclass:

  • myclass.cls
  • titlepage-english.def

Now the compiler always throws the following error:

File `titlepage-english.def' not found. \titlepage

Answer 1

Now I found the problem. After adding files into a tex-root directory, it is important to update the file name database. You can do that in MikTex console at Tasks>refresh file name database.
