As introduced previously in the chapter, the localization of a Pentaho report requires some resources to resolve the keys declared in the report elements. Starting from the Report Designer user interface, you can access the resources from the upper menu, in File | Resources.... Once selected, the Resource Editor will appear as shown in the following screenshot:

In few words, the Resource Editor is nothing more and nothing less than a manager of property files. By default, it contains the default file (translations.properties), but you will soon learn how to add and remove other property files. The property files defined here are part of the Pentaho report and for this reason are stored directly in the .prpt file.

Using the buttons on the right, you can create, edit, remove, and even import/export property files. We will not detail the behavior of each button here, because it is supposed to be easy to understand, considering that it is nothing less and nothing more...
