stackSentinel.py cost a lot of Disk space, 155G SLC file --> 3.0T is not enough

[ThreeIcug]

stackSentinel.py is a good tools, but it cost a lot of Disk space. I have 155G SLC file, but 3.0T free space is not enough for the whole process. I think it generate a lot of temp file, or some file is not used in the post process which can be removed in processing. Is there any way to use it as little space as possible.
