Hi,

actually I think that this is a kind of prejudice that often, but not
always holds, just as the prejudice that Mathematica is too slow for
numerics :-). I just opened a 4MB file with the standard eclipse text
editor and found it to be reasonable reactive. In this very case though,
it turned out to be true, see later...

In fact it was me who once suggested to give the workbench mathematica
source editor a try, because it has the nice feature that it knows the
mathematica syntax so you can select a cell-expression (as long as it is
intact) with a double click, which would be very convenient for the
process of correcting the corrupted notebook (you can try that with a
small notebook file). When you try this with a huge file, you will
notice that exactly that feature is turned of (and some others too) for
performance reasons. It seems to be controlled by the option setting
Window -> Preferences -> Mathematica -> Special -> "Ignore files greater
than", which you can increase to something larger than the file in
question. You will notice that then it will take ages to open huge files
and eventually the Java VM will run out of memory. There are ways to
tune that and you could also try to switch off the other niceties of the
Mathematica editor but altogether I think you will probably be better
off to use another editor and rely on just simple bracket matching as
Jens has suggested...
