Sounds like a memory leak due to poor coding. Define "certain amount".
Does it fail after a certain number of files every time?

Define "code stopped" too - is there actually an error message - can
you tell us what it is?

You could try inserting Help,/MEMORY in various strategic palces in
your code to watch the memory use.

You could try http://www.dfanning.com/programs/undefine.pro to make
unnecessary variables "vanish" to free up memory.
