Doing some cleanup on my Macbook Air with 128 SSD looking for big files to reduce space used. I found something named com.apple.coresymbolicationd that is 1GB in the library/caches folder I don't recall seeing before. Running Mountain Lion

What is this is there a way to clear it?

By the way I am using DaisyDisk to show the files and sizes

I don't know what it is, but it is safe to delete it, as this website proclaims: wootens.net/2012/12/30/… I always delete it anyway, nothing happens to me. Apparently, deleting it makes your Mac faster too! – Faiz Saleem Mar 2 at 0:40

Symbolication means replacing memory addresses with symbols (like functions or variables) or for example adding function names and line number information. It is used for debugging and analyzing crash reports.

/System/Library/Caches/com.apple.coresymbolicationd/data was also about 600 MB on my account, so I guess it's normal. Deleting files in cache folders is generally safe, and /System/Library/Caches/ is even excluded from Time Machine backups.
