[Q] Deleting Cached Data topic

Hi, I have a friend who decide to get this phone against my personal suggestion, now the issue is I that have no clue how to delete the cached data, I own Galaxy phones and Nexus, that I know where to go to delete the cached data, however I can't seem to find that option on HTC, nor if I boot on recovery I'll see this feature.

So the question is, How do I delete Cached Data on HTC?
