Here is a little known trick of NTFS file systems. It's called "data streams". D:\>del file.txt D:\>echo Some stuff > file.txt D:\>echo and its password >file.txt:pwd D:\>dir Volume in drive D is OS Volume Serial Number is A4BA-68F3 Directory of D:\ 24/09/2003 11:19p 13 file.txt (note the file size!) D:\>type file.txt Some stuff D:\>type file.txt:pwd The filename, directory name, or volume label syntax is incorrect. D:\>more <file.txt:pwd and its password D:\> I'm sure there are some interesting uses to be explored here to hide Oracle passwords! ;) Note: the hidden data stream name can be ANY filename string and is subject to security. This was used initially in NTFS to support the Mac resource fork file format in file servers. It is still there and won't go away any time soon as IIS uses it. MS Knowledge base article 105763 discusses this in detail. You can also search google for some details. Use "alternate data streams". Careful: this is used by some virus writers!!!
