Write a large Inputstream to File in Kotlin

My proposition is:

fun InputStream.toFile(path: String) {
    File(path).outputStream().use { this.copyTo(it) }
}

without closing current stream

InputStream.toFile("/path/filename")

also, do not forget to handle exceptions, for example if write permission is denied :)

You can simplify your function by using the copyTo function:

fun File.copyInputStreamToFile(inputStream: InputStream) {
    this.outputStream().use { fileOut ->
        inputStream.copyTo(fileOut)
    }
}
