 | == Freedesktop.org and Standard Directories ==
  |  | 
 |    |  | 
 | Many of the free and open source software projects that focus on desktop technology collaborate on shared specifications and software within the [http://freedesktop.org freedesktop.org] project.
  |  | 
 |    |  | 
 | One of these shared specifications is the [http://standards.freedesktop.org/basedir-spec/latest/ base directory specification] which defines a set of locations in the filesystem that can be used for portable desktop technology implementations.
  |  | 
 |    |  | 
 | KDE supports the base directory specification and the various [[../Environment_Variables|environment variables]] it prescribes in addition to the [[../KDE_Filesystem_Hierarchy|KDE filesystem hierarchy]]. A summary of KDE's implementation follows below, while the full specification can be read [http://standards.freedesktop.org/basedir-spec/latest/ here] on [http://freedesktop.org freedesktop.org].

 |    |  | 
 | == Application Data ==
  |  | 
 |    |  | 
 | Data that applications store which are specific to a given user are to be stored in the <tt>XDG_DATA_HOME</tt> directory. If the <tt>XDG_DATA_HOME</tt> environment variable isn't set, it defaults to {{path|$HOME/.local/share}} for local storage and {{path|/usr/local/share;/usr/share}} for system-wide files.
  |  | 
 |    |  | 
 | Some items that may be stored in <tt>XDG_DATA_HOME</tt> are files the user has put in the trash, mimetype definitions and associations, and application .desktop files.
  |  | 
 |    |  | 
 | The search path for system-wide directories can be defined by setting the <tt>XDG_DATA_DIRS</tt> environment variable to contain a list of paths.
  |  | 
 |    |  | 
 | == Configuration ==
  |  | 
 |    |  | 
 | Configuration information should be stored in the <tt>XDG_CONFIG_HOME</tt> directory. If the <tt>XDG_CONFIG_HOME</tt> environment variable isn't set, it defaults to {{path|$HOME/.config}} for local storage and {{path|/etc/xdg}} for system-wide files.
  |  | 
 |    |  | 
 | Some items that may be stored in <tt>XDG_CONFIG_HOME</tt> are application configuration files and application menu structure.
  |  | 
 |    |  | 
 | The search path for system-wide directories can be defined setting the <tt>XDG_CONFIG_DIRS</tt> environment variable to contain a list of paths.
  |  | 
 |    |  | 
 | == Cache Files ==
  |  | 
 |    |  | 
 | Temporary data caches can be stored in the <tt>XDG_CACHE_HOME</tt> location, which defaults to {{path|$HOME/.cache}}. There is no system-wide cache location, as such caches are always user-specific.
  |  | 
 |    |  | 
 | == Thumbnails == 
  |  | 
 |    |  | 
 | Thumbnails representing the contents of files for use in icons and other representations of files are to be stored in {{path|$HOME/.thumbnails}}. The structure and content of the thumbnails directory is defined in the [http://jens.triq.net/thumbnail-spec/index.html thumbnail specification].
