Upon first launch, Report Designer creates a .pentaho directory in the current user's home directory, and populates it with the following subdirectories:
Contains cached fonts, which speeds up report rendering
A cache directory that contains low-level options saved by the Pentaho Reporting engine
Contains both the default Pentaho-supplied report samples and content, and user preferences for the Report Designer interface
Contains the default Pentaho-supplied Report Design Wizard templates
Holds a single properties file that contains JNDI connection information. By default it has connection details for the Pentaho-supplied HSQLDB sample database
The following files contain various configuration options for Pentaho Reporting. The options are not particularly self-explanatory and their value limits are not obvious; therefore, you shouldn't change any options in these files unless you are following guidelines from Pentaho documentation or are assisted by a Pentaho support or consulting representative.
Contains options for the Report Designer client tool. It does not change any report options.
Contains global report rendering options for reports generated locally from Report Designer. Some of these options can be overridden in individual reports.
Contains global report rendering options for published reports that are generated on the Pentaho Server. Some of these options can be overridden in individual reports.
