Hi,

there are some "Converters" in a directory called just that within the
mathematica installation. Presumably they are used for import/export. On
my system after an export, there is no GIF.exe running anymore, but it
could well be that these are kept during evaluation and accumulate
memory within a loop. I think it would need Wolfram Research to correct
that or even comment on what exactly happens.

If your need is urgent and you want do dive deep into the internals,
could try to find out whether these converters are connected via
mathlink and whether you can find out which link object corresponds to
the GIF.exe. Then you could try what happens if you LinkClose or
UnInstall the corresponding link/libs. If you are lucky the next Export
starts a new one without the accumulated memory. It could just as well
make Mathematica crash...

I think this is not true, there is a binary GIF.exe coming with
Mathematica that most probably is called for import/exports...


hth,
