cache out x...some one help?

[drater]

I tried looking it up online and finding a better definition of what a "cache" is and tried to find out a prefered setting for Cache Out X. Can someone help me out. Maybe tell me what a cache is, what cache Out X does and why (if) I would need it. Should worry about anything? etc. Thanks. ((feeling like a computer moron right now))🙁

"Cache Out X clears out the cache entries on your machine, helping you recover valuable disk space on your machine. Set it to run at startup by placing it in your Login items in your System Preferences. Items removed include the caches in System, Users, and Library, along with the Internet Explorer download cache. Optionally clears the IE's history cache as well."

AKA it removes temporary files from your /users/yourname/library/caches/ folder. Its just a cleaning house utility. You don't really need it unless you are bleeding for more space.
