/private/var/folders not getting empty after reboot on macOS Catalina [duplicate]

/private/var/folders is not getting empty after reboot. The folder is 200 GB! I tried safe mode too and it didn't change.

How can I thin out the folder(s)?

Solution 1:

It's likely that unneeded files will be cleared if you perform a Safe Boot. And then restart normally.

However, a detailed account of cleaning out /var/folders can be found here,

which seems to indicate that not everything gets deleted on a Safe boot.

But unless you are desperate for storage space or experiencing some issues, I wouldn't recommend wholesale deletion of the entire contents.
