How to Hide ur Data using NTFS ADS feature

Hello friends, today let us discuss about NTFS Alternative Data Streams(ADS).
NTFS ADS are basically used to add extra information to a file. This extra data is know as metadata of that file.
This extra data is usually hidden and window OS doesnt have any tool to view its presence.
except win 2000 has a tool cat in resourse kit.

NTFS ADS can be used to hide data on ur pc without using any software. The NTFS ADS has many advantages as below:
1. There is no limit on the size of streams and there can be more than one stream linked to a normal file. 
2. ADS are not visible in explorer or via command prompt. In fact, their size is also not reported by Windows.
3. You can hide text data, images, videos and even Executables...!!
4. The streams can be attached to drives and folders too.

So now how to create a stream and hide data:
lets take an example here i shall create a stream to hide text data,
first goto CMD and type
notepad test.txt

hit enter, a notepad will open and it will ask u to save , save it and close.DONT TYPE ANYTHING IN IT.
now save and close it.now again open cmd and type following:
notepad test.txt:crypto.txt

hit enter it will again ask to save do it now type the text in notepad titled as text.txt:crypto.txt that u want to hide.

for example type anything like "Be a r3b3l not a p3bbl3"
now save and close.

now in above example the crypto.txt is the stream that we created and the data that we are hiding is "one thing is good about pain it lets u know that u are not d3ad yet." that is the data that we typed in test.txt:crypto.txt notepad.

Now if u go and check the size of test.txt file it will be 0 kb. no matter how much data u are hiding it will be 0 kb if.

Even if u use dir command to find hidden crypto.txt file u cant find it. 
The only way to find ur file is that u must remember the name of file and the stream name.
