/root/.cpanel/datastore folder question

Hi, i've noticed that the folder /root/.cpanel/datastore contains thousands of files, mostly of the form of Cpanel::Net::Whois::IP::Cached_XXX.XXX.XXX.XXX and some others. Is it safe to delete files older than XX days or weeks ? I've read that cpanel caches quota and some other info in this folder, but most of the files are in the form above (Cpanel::Net::Whois::IP::Cached_XXX.XXX.XXX.XXX). Is it ok to run from time to time something like : find /root/.cpanel/datastore/Cpanel::Net::Whois::IP::Cached* -type f -mtime +30 -exec rm {} \; in order to delete only whois data? best regards,
