Duplicate Files and Deleteing Languages

[pilotkid]

Is there a program that I can download that will go through all my files and find duplicate files so that I can delete them? Almost all my pictures (about 6000) have duplicates and its taking gb's of space off my hard drive. And is there a program that will let me delete all the useless languages that are installed when you install OSX, i forgot to go into options and unselect them all when I was installing it on my new hard drive...
Thank You

Monolingual will remove your languages. Don't use it to remove any architectures or any English languages though.

As for the duplicates, are you using iPhoto? Are you the duplicates split between a folder named Originals and one named Modified?
