fsv2 - 3D File System Visualizer
Prev |  | Next

# Menus

This section documents the various items accessible from fsv's top menu bar.

## File

Change root

  Restarts fsv in a different root directory. This brings up a directory selection dialog, and once a directory is specified, fsv will perform another scan and generate new file system geometry accordingly.

Quit

  Quits the program.

## View

This menu allows you to choose between fsv's various visualization modes. Each of these is a different approach to representing a file system. When you switch from one mode to another, the camera will automatically home in on the same node it was looking at before.

Map View

  Each node is a block which sits on top of its parent directory. (Viewed from above, it is basically a Venn diagram). The area covered by each block is proportional to the size of the corresponding file system node.

Tree View

  Nodes are separated into two categories: platforms and leaves. Platforms are directories which have been expanded for viewing; everything else is a leaf, which sits on some platform. The platforms are connected by branches, reflecting the file system's directory structure. The height of a leaf node indicates its size.

## Colors

This menu controls how colors are assigned to nodes.

By node type

  Assigns colors according to each node's file system entity type, which can be one of the following:

  - Directory - Also known as a "folder"

  - Regular file - Most nodes are of this type

  - Symbolic link - These just point to another file

  - Named pipe (FIFO) - Very rare

  - Network socket - Even rarer

  - Character device - Found in `/dev`

  - Block device - Also in `/dev`

  - Unknown - ???

By timestamp

  Assigns colors from a continuous spectrum representing time. The default setup employs a rainbow spectrum, coloring new files red, somewhat older files green, much older files indigo/violet, and so forth. Nodes which are too old (or too new) to occur within the spectrum's time range are shown darkened.

Preferences

  Brings up a setup dialog for the various color modes.
