I'm looking for a (portable) software or script that would allow me to draw a specific file structure as a tree, in Windows XP. Much like DOS tree command, but "prettier" (as a graph or diagram)

I already tried TreeSize but it doesn't suit my needs, as it does not offer any export options nor graphical tweaks.

Since 'tree' is not good enough, can you specify what you mean by prettier? :) – 8088 Apr 19 '11 at 9:07
I would like an image output, or to be able to change the way the tree is represented (horizontally instead of vertically for instance). I would like the links between folders to be plain, not ASCII characters ;) – Isaac Clarke Apr 19 '11 at 9:12
Why is my question closed ? It is NOT about file system usage ! – Isaac Clarke Apr 27 '11 at 8:14

I use a command-line program called "dot" to draw tree structures. To do that, you create a text file defining each file or folder as a unique node and the connections between them (parent to child)

Dot is a part of the Graphviz toolkit, documentation is online at:

It can output the drawing as PDF, SVG, PNG, JPG, etc.

Here's an example input file for the "dot" program (file name ""):

digraph "My File Tree Drawing" {
      /* paper size in inches */
      /* locate label at top of drawing */
      label="My File Tree Drawing";
      /* no directional arrow on connectors */
      edge [dir=none];
      /* nodes below are boxes (folders) */
      node [shape=box];
      folder1 [label="Folder 1 Name"];
      folder2 [label="Folder 2 Name"];
      folder3 [label="Folder 3 Name"];
      /* nodes below are ellipses (files) */
      node [shape=ellipse];
      file1 [label="File 1 Name"];
      file2 [label="File 2 Name"];
      file3 [label="File 3 Name"];
      file4 [label="File 4 Name"];
      /* parent -> child, to draw the tree */
      folder1 -> folder2;
      folder1 -> folder3;
      folder1 -> file1;
      folder2 -> file2;
      folder3 -> file3;
      folder3 -> file4;

To make this into a pdf, you would run the command:

dot -T pdf > test.pdf

This program makes great drawings of file trees (or any tree / graph structure). The part that requires the most work is making the input *.dot file. I usually write a script to look through the file tree and output a text file formatted similar to "" above. Make sure that ALL NODE NAMES ARE UNIQUE (even if the label/file/folder name is the same). Another useful thing to know, each line in the *.dot file can come in almost any order - if any are duplicates, the last one will override the previous ones.

Additional "dot" documentation is available at

Thank you very much, I'll try this ! – Isaac Clarke Apr 29 '11 at 7:24

Treeviz - it's a Java app. I'm sure it will work on Windows, but I just happened to be on a Mac.

The trees are interactive. You can move things around and such with your mouse.

Yes, it's supposed to run on windows ;) I can't seem to launch it though, it throws a "MissingFieldException" – Isaac Clarke Apr 29 '11 at 7:54
