Too short

I guess that there is a reason these answers are not in the FAQ and I just wasted my and your time ?

1) There is a method to read a file in NETSCAPE (through the Java class)

2) depending on what you want to do with the file, this me be a solution:
a) create a separate (invisible) frame
b) use parent.FRAMENAME.location = "yourfile.htm" to load the file in that frame
c) The file is loaded, you can not read the lines from within Javascript (but you can read all the hrefs and anchors
d) there are no security violations when the file is on the same host (and path?) as the loading file.
e) very kinky is to have javascript in that file that is being loaded, code that is activated with an onLoad()
f) Even more kinky is to have the loaded file after doing whatever work it needed to do, perform a document.location = "anotherfile.htm" ON ITS OWN FRAME. I used this method to make a search application with "unlimited" data input: the loaded scripts output their data to a common frame.

To read and write into a flat file use Jscript's ActiveXobject. This solves the problem

Not technical enough

there is a way in netscape to do this and I am sure Internet explorer can also. Below I have code that can read any file on the clients machine, but only with their approval. This code only works on Netscape:

function readFromFile(filename) {
var text = ""
var filechar
var file = new java.io.File(filename)
var FileReader = new java.io.FileReader(file)
filechar = FileReader.read()
while (filechar != -1) {
text = text + String.fromCharCode(filechar)
filechar = FileReader.read()
return text
