What is a KOTLIN_BUILTINS file?

KOTLIN_BUILTINS files mostly belong to kotlinc. The KOTLIN_BUILTINS file is a metadata storage file used by the Kotlin compiler to hold Kotlin built-in declarations that define the core functions, classes, and properties of the Kotlin language.
  • It stores precompiled language definitions that the compiler reads during the build process.
  • It is not meant to be edited directly by users since the format is built for internal use.
  • It ensures that built-in functions and types are recognized properly during both compilation and runtime reflection.
  • FilExt.com note: To inspect these files, use an IDE with Kotlin support such as IntelliJ IDEA. More details can be found at the Kotlin official website.
