# Can I use \input inside an \include?

I know it is not possible to nest one \include inside another, but what about \input? Is it possible to have something like:

\documentclass{article}

\begin{document}

\include{file1}

\end{document}


and then in file1.tex:

\section{samplesection}
\input{file2}


in file2.tex;

\section{samplesection2}

Did you try to do this? –  Sigur Apr 10 '13 at 22:04
I did, and it worked, but I wanted to know if it was because of luck (or such a small example) and if I was going to have any problems in the future for using it this way –  Mario S. E. Apr 10 '13 at 22:10
You can nest \input{macros} and You can't nest \include{files} files. See "When should I use \input vs. \include?" : Martin Scharrer Answer –  texenthusiast Apr 10 '13 at 22:16

\include commands may not be nested: They may only appear in the main processing file. However, an \input command may be given within a file that is \included.
