[X-Newbies] Getting rid of remnants of old uninstalled programs

[Joshua Varghese]

Hello everyone,

I'm 12 years of age and I'm quite new to the world of the mac. I have  
been using a MacBook for the last 2 months.

I have tried out various programs, a lot of them I didn't like and  
deleted. I then found that there were still files on my computer that  
belonged to the programs that I deleted.

Can someone give me some pointers as to how I can get rid of these  
files.

Thanks,
Joshua.
