Check if a directory exists in Kotlin

This post will discuss how to check if a directory exists in Kotlin.

When checking for a directory’s existence, three outcomes are possible:

The directory exists.
The directory doesn’t exist.
The directory’s status is unknown as the program does not have access to it.

Each of the following solutions returns true if the directory exists; false otherwise.

1. Using `File.isDirectory()` function

To check for the directory’s existence in Kotlin, you can use the File.isDirectory() function. It returns true if the directory exists; false otherwise. A typical invocation for this method would look like:

import java.io.File

fun main() {

val directoryPath = "/var/kotlin/"

val file = File(directoryPath)

if (file.isDirectory) {

println("File is a Directory")

} else {

println("Directory doesn't exist!!")

}

2. Using `Files.isDirectory()` function

Alternately, you can use the static function Files.isDirectory() to check for a directory’s existence. It returns true when the specified path points to a directory. This function is demonstrated below:

import java.nio.file.Files

import java.nio.file.Paths

fun main() {

val directoryPath = "/var/kotlin/"

val path = Paths.get(directoryPath)

val isDir = Files.isDirectory(path)

if (isDir) {

println("File is a Directory")

} else {

println("Directory doesn't exist!!")

}
