Is it safe to delete core dump files from Mac?

I have a Macbook Pro running masOS Sierra 10.12.2. I recently started clearing out storage on my computer by moving majority of my files and photos to an external hard drive. However, I can't seem to figure out why "system" is taking up so much space.

I ran OmniDiskSweeper and I found 383.4 GB of "core" files. What are these and is it safe to delete them?

The /cores folder is where OS X stores Core Dumps. These are files that are intended for developers to troubleshoot and diagnose faults in their software. They are generated as software crashes. If you're not a developer, or aren't testing software for a developer, then these files serve no purpose for you.

You can disable creation of core files with following command,

sudo launchctl limit core 0 unlimited

You can delete all existing core files using command below,

sudo rm -f /cores/core.*
