Why i cannot see a file which copied from cmd to android sd card?

I am trying to copy a file from my pc to the Samsung Table S4 SD card via cmd(Windows 7).I use the xcopy command.Everything seems to be okay.A message "1 file copied " appears and when i try to overwrite the file to the folder located in SD, file exists.
However, i cannot see the file by entering the SD contents from MyComputer.
Also when i type dir in the cmd command , file does not appear.
IF i manually copy the file (by copy and paste from PC to SD card), then file appears in the folder located in SD CARD.
Why does it happen?

Creating a folder with file in Android's internal storage

i'm trying to create a folder with a .csv file inside in android internal storage, but the folder doesn't appear in the regular file explorers.
The code is the following.
private String FOLDER_NAME = "app_folder";
File folder = new File(Environment.getDataDirectory().getAbsolutePath() + File.separator + FOLDER_NAME);
if( !folder.exists() )
folder.mkdir();

but the folder doesn't appear in the regular file explorers.
That is because internal storage cannot be viewed by any sort of file explorer, except on emulators or rooted devices.
File explorers — on-device and desktop — usually examine external storage.

Android: find a file created in AVD

My application has a function of creating an xls file. After that I need to access that file manually. Now, the problem is, when i run the app on my device, I am able to locate the directories and my xls file in internal storage.
But when I try to run that in the AVD, I am not able to find the file. I also viewed file explorer but there also, I wasn't able to find my file.
Where does the file exists when created in AVD?
Below is the code :
File myDir = new File(Environment.getExternalStorageDirectory()+ "/PB/automation/mydir/");
myFolder.mkdirs();
File file = new File(myFolder, "demo.xls");
Trust me, there is nothing wrong with the code.
Below is the file explorer view :

Files directory in android

I have a file into "files" directory in my android project in eclipse, but when run the application in my device or in a device emulator, i don't find this directory
i want to put this file in /data/data/MYPACKAGE/files/mifile.txt during the installation

put it under assets folder and use getAssets() to access it
InputStream inputStream = getAssets().open("files/myfile.txt");
this will return the InputStream from the file then you can read it.

You could use getRessourceAsStream(String path) or simply use the assets folder and getAssets()

How to Create Directory in Phone Memory in android Emulator in Android

how to create directory in phone memory in android emulator not in SDCard

Following code can help you to create directory in phone's internal memory:
File f = new File(getFilesDir()+"/abc");
if(!f.isDirectory())
Log.d("dir", f.mkdir()? "Directory created": "Directory not created");
Actually getFilesDir() returns path to internal memory's file folder and allows you to create further files and/or directories inside.
