How to safely handle large size KNIME folder (71.4GB) under /private/var/folders/q6/v.../T/knime_...

Mac OS Sequoia 15.6, KNIME 5.70.

When launching KNIME, the path I have set is an SSD, and as shown on the menu bar /Volumes/X31/KNIME – This is where I figure any workflows and their data are being saved each day, including Parquet Reader/Writers, etc. I can see the folder on there titled with my workflow being about 39 GB.

But I got a warning on my Mac that I was running out of space, and had to do some digging where I saw a path of */private/var/folders/q6/v…/T/knime_my_project_16757 totaling 71.4GB.*

What is this and can it be safely deleted?

If so, and I delete it when KNIME is fully closed closed, will this reset any saved executed nodes I have?

Lastly, if KNIME is writing to this location, is there a way to redirect that to be on my SSD instead?
