Kotlin – Delete File

Kotlin – Delete File

Deleting a file in Kotlin can be performed using the delete() method of the File class from the java.io package. This method deletes the file or directory denoted by the File object.

In this tutorial, we’ll show you how to delete a file in Kotlin, with an example.

Steps to Delete a File in Kotlin

Here is how you can delete a file in Kotlin:

1. Import the File class from the java.io package.
2. Specify the file path of the file you want to delete.
3. Create a File object using the file path.
4. Use the delete() method to attempt to delete the file. This method returns true if the file was successfully deleted, and false otherwise.
5. Include proper error handling to ensure the program can handle any issues that arise during the file deletion process.

Kotlin Example Program to Delete a File

Below is an example of how to delete a file named 'example.txt'.

Main.kt

import java.io.File

fun main() {
    val filePath = "example.txt" // Replace with the path to your file

    val file = File(filePath)
    val result = file.delete()

    if (result) {
        println("File deleted successfully.")
    } else {
        println("Error occurred while deleting the file or file does not exist.")
    }
}

Output

File deleted successfully.

The output will confirm whether the file was successfully deleted or if an error occurred.
