Huge size folder under wp-content\cache\ How can i do it?

[~/public_html]# cd wp-content
[~/public_html/wp-content]# du -sh *
4.0K advanced-cache.php
15G cache
16K crayon-syntax-highlighter
0 debug.log
4.0K index.php
12K kboard_captcha
76K kboard_htmlpurifier
3.6M languages
8.0K mu-plugins
137M plugins
16M themes
4.0K upgrade
3.1G uploads
12K wpo-cache
[~/public_html/wp-content]# ls -al cache/
total 16
drwxr-xr-x 4 user user 4096 Jul 20 19:06 ./
drwxr-xr-x 13 user user 4096 Jul 20 19:07 ../
drwxr-xr-x 3 user user 4096 Jul 20 19:06 wpo-cache/
drwxr-xr-x 6 user user 4096 Jul 20 19:06 wpo-minify/
[~/public_html/wp-content/cache]# du -sh *
31M wpo-cache
15G wpo-minify

I already set the cache lifetime to no more than 24 hours in WP-Optimize > Cache > Cache Settings. However, 15G files are piled up. Deleting it seems to cause problems. How do I delete it?
