1. Open Command prompt (assuming ur in a drive formated with NTFS filesystem)

2. Use more command to enter some data…..

more > personal.txt: password

ur sensitive info and press CTRL+Z to save>

3. The above command creates a file named with personal.txt in the current dir

4. The "password" is called an alternate data stream present in personal.txt.

The data u entered using more command is actually stored under

"personal.txt: password" not in "personal.txt" as a result when u do

directory listing using dir command u ll notice the size of personal.txt is zero!!!!

5. And to retrieve the sensitive info u can use more <>

DOS)

Try opening the personal.txt using notepad………to ur surprise u see no content……….

This is becoz notepad is opening personal.txt not personal.txt: password .
