File manipulation in JavaScript

[Froggy_Jo]

I have a split screen HTML display. In the bottom half, I have a
series of file names with hyperlinks. In the top half, I want to
display the file selected. However, it seems I can only do this if
the file has a TXT extension. If this is the case, what Javascript
could I write which would take the file, copy it to a temporary area
and rename it as a TXT file. It should then delete the file when I
select a new file or close the window. Sorry to ask for a solution,
but I'm not really a Java programmer. I could do it in Fortran!!!

Client-side JavaScript can't manipulate files directly, either on the
server or on the client.

If all you want to do is display the contents of a link in the bottom
frame in the top frame (let's call it "Top") then all you need is:

<a href="somefile.ext" target="Top">View somefile.ext in the frame
above</a>

Some file types will not display in a frame in a web browser and some
will on some browsers and not on others. It depends completely on the
target browser and the applications installed and registered in the OS
to handle various MIME types.
