Environment.getExternalStorageDirectory() this method is deprecated in API level 29 and it will not allow to create a directory/file on given path.

Below code is working for creating directory and downloading file from /res/raw directory.

If your device have Android 10 (API Level 29) or greater it will download your file on below location

File manager--> Storage --> Android --> data --> com.yourapp.packagename --> files --> FOLDER_NAME --> file_name.png

private void downloadFileFromRawFolder(){
try {
                InputStream in = getResources().openRawResource(
                        getResources().getIdentifier("file_name",
                                "raw", getPackageName())); // use only file name here, don't use extension
                File fileWithinMyDir = new File(checkFolder(), "file_name.png"); //Getting a file within the dir.
                Log.e("FILEPATH ", "fileWithinMyDir " + fileWithinMyDir);
                FileOutputStream out = new FileOutputStream(fileWithinMyDir);
                byte[] buff = new byte[1024 * 1024 * 2]; //2MB file
                int read = 0;

                try {
                    while ((read = in.read(buff)) > 0) {
                        out.write(buff, 0, read);
                    }
                } finally {
                    in.close();
                    out.close();
                }
                Log.d(TAG, "Download Done ");
            } catch (IOException e) {
                Log.e(TAG, "Download Failed " + e.getMessage());
                e.printStackTrace();
            }

}
