Read the file content from resources like:

val fileContent = MySpec::class.java.getResource("/myFiles/file.html").readText()

You can use this copyTo in Kotlin like:

 fun InputStream.copyTo(
    out: OutputStream,
    bufferSize: Int = DEFAULT_BUFFER_SIZE
): Long

This will Copies this stream to the given output stream, returning the number of bytes copied

Note: It is the caller's responsibility to close both of these resources. Source: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/java.io.-input-stream/copy-to.html

Delete it using:

val file = File(yourFIlePath)
file.absoluteFile.delete()
