This conversation helped me so much!! I was always confused on why sometimes my batches would just keep writing over the same file over and over again…and I knew about the diagnostic run…but just never used it and figured it was a glitch in the system. I would then go back on my template and play around….and potentially making them smaller in file size where it then would start working. After reading this and doing the test for myself…I finally found the problem that has been perplexing me for years!!
