topsStack steps, delete directories no longer used

[chofst]

Hi,

I am generating a large number of interferograms with topsStack, and am using a lot (majority) of my memory on the steps. Are there certain directories that can be erased after certain steps? I am currently processing run_13 and am not sure I need to keep all the directories from the earlier steps to complete the rest of the steps. I appreciate any help and guidance.
