编译文档后如何找到文件名？

Question

我找到了样本海报的一部分。当我申请时，他问我：“输入文件名？”你能告诉我在哪里可以找到文件名吗？

\documentclass[paper=a4paper,landscape,dvipsnames]{umbcposter}
\begin{document}
\newcommand{\mytitle}{
\begin{tabular}{c}
    \LARGE\sc This is the title \\[0.6ex]
    \Large\sl Rouben Rostamian\\
    \Large UMBC
\end{tabular}
}
\posterinit{
%grid,
background style = {left color = Apricot, right color = white},
title = {\mytitle},
right logo,       
left logo,        
box/border style, 
box/header style, 
box/body style = {bottom color=blue!10, top color=red!5},
box/all rounded,
}
\boxit{col = 0, at top, name=box1}{Title of Box 1}{
\begin{itemize}
    \item col = 0
    \item at top
    \item name = box1
\end{itemize}
}
\boxit{col = 0, below of=box1, name=box2}{Title of Box 2}{
\begin{itemize}
    \item col = 0
    \item below of = box1
    \item name = box2
\end{itemize}
}
\end{document}
