Properties files

Last modified: 08 March 2021

Properties files are text files with the .properties extension, containing localization strings in the form of key and value pairs, that can be accessed and rendered in the UI. These files are marked with the icon Properties file.

IntelliJ IDEA also recognizes properties files in XML format. They are marked with the icon XML properties file.

Several properties files with the same base name and a language-specific suffix can be combined into a resource bundle for convenience.
