How to create and delete folders and files on Android

This is also relatively simple, just upload the code

/**
  *
  Create a directory file

  */

public

static 
void createPath(String path) {

  File
 file = new

File(path);

  if

(!()) {

   ();

  }
 }

Deleting files is relatively simple, but deleting folders is not that simple, especially it contains many sub-files. You need to delete it one by one.

/**


  *
  Delete all contents of the folder


  *


  */


public

void deleteFile(File file) {


 


 if

(()) { //
 Determine whether the file exists


  if

(()) { //
 Determine whether it is a file


   ();
//
 delete()method You should know It means deletion;


  }
else

if 
(()) { //
 Otherwise if it is a directory


   File
 files[] = (); //
 Declare all files in the directory files[];


   for

(int i = 0; i < ; i++) { //
 Traverse all files in the directory


    (files[i]);
//
 Put each file 用这个method进行迭代


   }


  }


  ();


 }
else

{


  //


 }


}

If your files are stored in the SD card, you can check out the previous article first

String filespath = ().getPath(); // Get the path to the private folder

The above method of creating and deleting folders and files on Android is all the content I have shared with you. I hope you can give you a reference and I hope you can support me more.
