How to delete the internal storage file in android?

Question

I used the Android internal storage to save the file for my application (using openFileOutput ), but I would like to delete this file, is it possible and how?

Answer 1

 File dir = getFilesDir(); File file = new File(dir, "my_filename"); boolean deleted = file.delete(); 

Answer 2

I know this is a bit like the old one, but the docs say:

 deleteFile("filename"); 

but not:

 File.delete(); 

What if you are already using:

 getFilesDir(); 

has the meaning.

Answer 3

You should always delete files that you no longer need. The easiest way to delete a file is to open an open call to the delete () file link.

myFile.delete() ;

If the file is saved in internal memory, you can also ask the context to find and delete the file by calling deleteFile ():

myContext.deleteFile(fileName);

Note. When a user uninstalls your application, the Android system deletes the following: All files stored on the external storage All files stored on the external storage using getExternalFilesDir() . However, you must manually delete all cached files created with getCacheDir() on a regular basis, as well as regularly delete other files that you no longer need.

Answer 4

Use delete file method

Answer 5

 new File(mUri.toString).delete(); 

Answer 6

If you want to delete all files from a folder, use the following function:

 private void deleteTempFolder(String dir) { File myDir = new File(Environment.getExternalStorageDirectory() + "/"+dir); if (myDir.isDirectory()) { String[] children = myDir.list(); for (int i = 0; i < children.length; i++) { new File(myDir, children[i]).delete(); } } } 

The folder must be present in storage. If not, we can check another coding for it.

  if (myDir.exists() && myDir.isDirectory()) { //write same defination for it. } 

Answer 7

  void clearMyFiles() { File[] files = context.getFilesDir().listFiles(); if(files != null) for(File file : files) { file.delete(); } }
