spoofing filesize

okay, so i have these 12gb files, and i want to make them look like they are only 4kb.  i dont want windows to see them shen colculating disc space.  how do i do this in an ntfs filesystem.

Delete or move.

Otherwise once you do something like that either the files are deleted, your file system is corrupt or both. Why would you want to do something stupid like that anyways? Shit's crazy.

Hiding CP, huh?  Just encrypt it and re-name it to something like one of the Java .jar files to hide it.  Even if the FBI finds it, you should have used strong encryption, and so claim innocence that some .jar file seems to be an encrypted cache of something.  "Honest, Agent Smith, I had NO IDEA that that .jar file is actually encrypted!  I have NO IDEA what's in it!  Some haxxor must have rootkitted me and put it on there!  I just had a rootkit removed a few months ago!"  Etc.  Having no idea that such a file was there, then they can hardly expect that you know the encryption password, right?  If they can't crack it, then they can't charge you with having CP, right?  Of course RIGHT!

>I just had a rootkit removed a few months ago!
Yeah sure. The more you lie the more unplausible you get and the worse your situation gets. Why not just use truecrypt and make a steganographically hidden volume in another hidden volume? That way you can savely show them the openly visible encrypted volume, they see that it holds only boring personal stuff of yours and there's no way to prove that there's another hidden encrypted volume in there.

I'm sure that this will prompt a "google motherfucker do you speak it?", but using steganography requires a lot of overhead as you're hiding stuff in the minority information of the data cache.  How much of a data cache is required to hide 12GB of information?

I can see hiding a bit of b& pr0n inside a set of otherwise innocuous pr0n.  Your advice probably makes more sense.

OH GOD JUST FUCKING LEARN ABOUT NTFS ALTERNATE DATA STREAMS AND LEARN2/PROGRAM ALREADY

Ok well, in the case of Truecrypt, it isn't strictly steganography as implemented in Steganos years ago for example. It's still a method that features comparable security without the huge overhead. So basically hiding 12 GB of data would require 12 GB of space plus some space to make the outer container. Dunno, I'd choose maybe 15 GB or so.

Sure, if the only persons you want to hide your data from are your parents and your sister...

go ask /prog/
