Make directory tree with folders and files in Tikz

Question

I borrowed the code from @Gonzalo answer. I want to make directory tree with folders and files like the given the following picture.

The MWE is below:

\documentclass[border=10pt]{standalone}
\usepackage{forest}

\definecolor{fblue}{RGB}{92,144,192}
\definecolor{fgreen}{RGB}{34,162,70}

\newcommand\myfolder[2][fblue]{%
\begin{tikzpicture}[overlay]
\begin{scope}[xshift=20pt]
\filldraw[rounded corners=1pt,fill=#1,draw=white,double=black]
  (-23pt,10pt) -- ++(3pt,5pt) -- ++(18pt,0pt) -- ++(40:3pt) -- ++(9pt,0pt) -- ++(-40:3pt)
  -- (20pt,15pt) -- (23pt,10pt) -- cycle;
\filldraw[rounded corners,draw=white,double=black,top color=#1,bottom color=#1!30]
  (-22pt,-12pt) -- ++(44pt,0pt) -- (25pt,12pt) coordinate (topr) -- ++(-50pt,0pt) coordinate (topl) -- cycle;
\end{scope}  
\end{tikzpicture}%
\makebox[35pt]{\raisebox{-3pt}{{\ttfamily/#2}}}%
}

\begin{document}

\begin{forest}
  for tree={
    font=\sffamily,
    minimum height=0.75cm,
    rounded corners=4pt,
    grow'=0,
    inner ysep=8pt,
    child anchor=west,
    parent anchor=south,
    anchor=west,
    calign=first,
    edge={rounded corners},
    edge path={
      \noexpand\path [draw, \forestoption{edge}]
      (!u.south west) +(12.5pt,0) |- (.child anchor)\forestoption{edge label};
    },
    before typesetting nodes={
      if n=1
        {insert before={[,phantom,minimum height=10pt]}}
        {}
    },
    fit=band,
    s sep=12pt,
    before computing xy={l=25pt},
  }

Questions

1. How to remove / from folders names and properly aligning them.
2. Reducing vertical space between two file names

Any help will be highly appreciated. Thanks

Here's an updated version.
