What is a .PROPERTIES file?
A .properties file stores key-value settings, mainly in Java applications.
- Did you know
- Java has used .properties files for configuration and translations since the 1990s.
- Before Java 9 a .properties file had to be encoded in ISO-8859-1, with any other character written as a \uHHHH escape.
- Grouped into ResourceBundles, these files are Java’s standard way of translating an application into different languages.
- What Analyser reads
- Identify configuration files: TOML, INI, .env, CONF, CFG, and Java properties.
- Depth of analysis
- .PROPERTIES is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .PROPERTIES file
- Drag a .PROPERTIES file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
