FileSystemObject - reading a picture file

P: 3

i am trying to use the fileSystemObject methods to read a picture file as a text (forcefully), store it in a variable, and then i try writing it back to a file and opening it up with a text editor. I just don't get why they get corrupted:

var ForReading = 1;
var TriStateUni = -2;
var fso = new ActiveXObject("Scripting.FileSystemObject");
var newFile = fso.OpenTextFile(localPath, ForReading, false, TriStateUni);
var tempText = newFile.readAll();
var qqq = fso.CreateTextFile ("C:\\xxxxxxxxx22.txt", true);
qqq.Write (tempText );

what i get in the xxxxxxxxxx22.txt file is exactly the head and tail portions of the original .jpg file. and a whole chunk of blanks/empty spaces in the middle.

when i do a tempText.length, the length is the same as the amount of characters in the original .jpg file.

other than this, is there any other better method in Javascript that i can use to open up any files (not just jpg) as text, ie, like using notepad to do so? and hopefully, cross browser?

i'm doing a project and the aim of having any file in a var is to do encryption on it..

thank you to anybody who can help me....

For security, file reading and writing is not a common feature of browsers, i believe only IE has it, and that still has security limitationes, like only letting the script run if the client says so. And the only way to read/write files is using the FileSystemObject.
