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.

How do you open KOTLIN_BUILTINS files?

You need a suitable software like kotlinc to open a KOTLIN_BUILTINS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your KOTLIN_BUILTINS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KOTLIN_BUILTINS file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert KOTLIN_BUILTINS files:

kotlinc
See the previous paragraphs to learn more about the main application. KOTLIN_BUILTINS files are often referred to as kotlinc developers because this type of file is primarily created or used by this software.
Kotlin Compiler (kotlinc)
*.KOTLIN_BUILTINS files store metadata about the Kotlin language. They contain built-in declarations and are essential for the Kotlin compiler (kotlinc) to function correctly. These files, comprising 100% of all files with this extension, enable the compiler to understand and utilize Kotlin's standard library and intrinsic language features. They are crucial for code analysis, compilation, and execution within the Kotlin ecosystem. This file format is classified as Developer Files.

KOTLIN_BUILTINS file format:

To find out what program is needed to open KOTLIN_BUILTINS files, you need to determine the file format. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the KOTLIN_BUILTINS files produces the following result:

You will often come across the KOTLIN_BUILTINS file type. This is primarily used by a single program. But the following two file formats are common:

95% of all KOTLIN_BUILTINS files are Kotlin Builtins metadata files. If you open these files in a text editor, you will see only illegible characters. KOTLIN_BUILTINS files can be up to 29 KB in size, but are often around 640 bytes - 16 KB. The file type is very recent. The keywords kotlin, Iterator, Annotation, Boolean, collections, Cloneable, clone, Function, value, equals, String and Unit are typical for these files. The following filename is common: kotlin.kotlin_builtins or collections.kotlin_builtins. Such KOTLIN_BUILTINS files store data about annotation, internal, reflect, ranges and coroutines.

The remaining 5% of all KOTLIN_BUILTINS files are files with no common format. Drag & drop your file here to see the file format and a preview of your KOTLIN_BUILTINS file!

a kotlin_builtins metadata file is a special file format and should only be edited and saved with the appropriate software.

How to solve problems with KOTLIN_BUILTINS files

Associate the KOTLIN_BUILTINS file extension with the correct application.
Update your software that should actually open metadata files. Because only the current version supports the latest KOTLIN_BUILTINS file format. Search, therefore, e.g. on the manufacturer website after an available kotlinc update.
To make sure that your KOTLIN_BUILTINS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
