Setting fontsize for dirtree globally

Question

I am using the \dirtree package to present some directories in my document. Is there a way to globally set size of \dirtree contents to someting other than what the document is set to? I can change the size for each directory tree separately by using something like:

\begin{tiny}
\dirtree{%
    .1 dir1.
    .1 dir2.
    .2 dir3.
}
\end{tiny}

Is there a way to define this is the preamble?

Only other option that I can see is to create a Macro in TeXstudio.

Answer 1

You could define

\newcommand\mydirtree[1]{{\tiny\dirtree{#1}\par}}

then use \mydirtree{.....}
