you can read files using data binding but i guess it's not what you're looking for. if you need to read files that contains data you want to show on the page u can use it.
about writing, i guess you can't do it.
batalf, in IE5 you have VML (Vector markup language) that gives you the ability to draw graphics.
Client side JavaScript can read files only if the text are wrapped in *.js (JavaScript) - file. Client side JavaScript can not write to files.
If you want to READ from a textfile on the web-server, you can use a "faceless" Java Applet to do the reading, and then use JavaScript to call a function in the Java applet to obtain the text from the file.
If you want to READ/WRITE a textfile, you will have to use Common Gateway Interface (CGI) / Java Servlets or similar. This also means that you have to have pretty good controll over the Web-Server. (This approach will not work if you use an ISP).

As far as I know Javascript is unable to 3 things:
- read and write from files
- showing graphics
- perform networking
But if I'm wrong, I would be happy to know how to read/write to files in Javascript....but this is what I have read.
