26 test.txt:hidden:$DATA

yes i did create the file before i tried opening in notepad....i followed the steps you said for test.txt

NOTE THIS

C:\>notepad test:hidden.txt
(THIS showes my hidden text)

C:\>notepad test.txt:hidden.txt
(THIS doesnt work, says file doesnt exist..????)

LOL :rofl: Look at what your drive contents :

17 test:hidden.txt:$DATA
28-06-2009 22:58 17 test.txt
26 test.txt:hidden:$DATA

So, you have created a ADS named "hidden.txt" in the file "test" (without ".txt" extension) and you have also created an ADS named "hidden" (without the ".txt" extension) in the file "test.txt". That means you can either use :

(1) notepad test.txt:hidden or
(2) notepad test:hidden.txt

And not :

(1) notepad test.txt:hidden.txt or
(2) notepad test:hidden

Directory of C:\

^MY date and time didnt change???? how come it should? i checked, the text is added in hidden.txt

Reason is mentioned in the first part of this reply.
When you added more text to the "hidden.txt", you added it to the ADS "hidden.txt" attached to "test" not "test.txt". So, the time-stamp of "test" changed and not "test.txt".
Try to modify "hidden" and not "hidden.txt", like this :

notepad test.txt:hidden

You will see, the time-stamp of test.txt will change.

You probably messed up with the extensions while creating the file or the ADS. Delete both and start again, as mentioned in the article.

As mentioned in the article, it won't work on an FS which does not support ADS e.g. FAT32 and FAT16. But it works fine if the source and destination file-sytems, both support ADS e.g. transferring from NTFS to Mac HFS is fine.

Nothing wrong, may be GMail uses an FS that does not support ADS. So, when your file was stored in GMail, all alternate data streams were lost. So, when you downloaded the file and tested it, it had no ADS !

Extract all the "*.exe" from "usr\local\wbin" folder inside the zip file to your %WINDIR%\system32 folder.
Then you can directly use the *nix utilities from command prompt. :)

Re: Hide Data WITHOUT Steganography
 
You downloaded the UnxUtils.zip file, right ?? (The binary file, not the source !)
Then inside the zip, there are two folder : bin and usr.
The executables are @ : usr->local->wbin

Re: Hide Data WITHOUT Steganography
 
ok i got the binary file not the source (which i did last time), extracted the exes from usr>local>wbin>
to C:\Windows\System32\
but yet the cat command in not recognized...?
what could be wrong? i checked, cat is there....

Re: Hide Data WITHOUT Steganography
 
May be something with the permissions, that's a really annoying feature in Vista. Allow full control to all the exes and see if they work.
Or, may be C:\Windows\System32 is not listed in your PATH environment variable, which is nearly impossible.
