      Deleting Files

      Deleting Files in Java

      To delete a file in Java, you can use the File.delete() method. This method deletes the files or directory from the given path.

      Syntax

      Following is the syntax of deleting a file using File.delete() method 
      File file = new File("C:/java/hello.txt");
      
      if(file.exists()){
         file.delete();
      }

      Deleting File from Current Directory

      Following is the example to demonstrate File.delete() method usage to delete an existing file in current directory

      Example

      package com.tutorialspoint;
      
      import java.io.BufferedWriter;
      import java.io.File;
      import java.io.FileWriter;
      import java.io.IOException;
      
      public class FileTest {
        
         public static void main(String args[]) throws IOException {
            BufferedWriter out = new BufferedWriter (new FileWriter("test.txt"));
            out.write("test data");
            out.close();
      
            File file = new File("test.txt");
            if(file.exists()) {
               boolean success = file.delete();
      
               if (success) {
                  System.out.println("The file has been successfully deleted."); 
               }else {
                  System.out.println("The file deletion failed.");
               }        
            }else {
               System.out.println("The file is not present."); 
            }
         }
      }

      Output

      The above code would create file test.txt and would write given numbers in binary format. Same would be the output on the stdout screen.
      This will produce the following result 
      The file has been successfully deleted.

      Deleting File That Does Not Exist

      Following is the example to demonstrate File.delete() method call to delete an non-existing file in current directory. As file is not present, it returns false as result.

      Example

      package com.tutorialspoint;
      
      import java.io.File;
      import java.io.IOException;
      
      public class FileTest {
        
         public static void main(String args[]) throws IOException {
            File file = new File("test1.txt");
            boolean success = file.delete();
      
            if (success) {
               System.out.println("The file has been successfully deleted."); 
            }else {
               System.out.println("The file deletion failed.");
            }    
         }
      }

      Output

      The above code would create file test.txt and would write given numbers in binary format. Same would be the output on the stdout screen.
      This will produce the following result 
      The file deletion failed.

      Deleting All Files From Given Directory

      Following is the example to demonstrate File.delete() method usage to delete all files in given directory recursively.

      Example

      package com.tutorialspoint;
      
      import java.io.File;
      import java.io.IOException;
      
      public class FileTest {
        
         public static void deleteFiles(File dirPath) {
            File filesList[] = dirPath.listFiles();
            for(File file : filesList) {
               if(file.isFile()) {
                  file.delete();
               } else {
                  deleteFiles(file);
               }
            }
         }
         public static void main(String args[]) throws IOException {
            
            //Creating a File object for directory
            File file = new File("D:\\test");
            
            //List of all files and directories
            deleteFiles(file);
            System.out.println("Files deleted.");
         }
      }

      Output

      The above code would create file test.txt and would write given numbers in binary format. Same would be the output on the stdout screen.
      This will produce the following result 
      Files deleted.
