Thanks for the reply.
Yes I am running it from the stick, and have tried different sticks, but always with the same result that any file over 100mb gets near completion of loading then reports insufficient memory. I am confused as the manual says you can run direct from the stick with larger files, but when you choose this option, it still appears to need to load on to the pendant's internal memory before running. I need to find the instruction to bypass this step, or as you point out, learn how to make it as more than one part. I am reluctant to go down that route until I have ascertained beyond doubt that it is not possible run files larger than 100mb using the pendant.
