Sorry for jumping in, Rita; I should have waited for you to respond.
joemike's solution is a good one if you know precisely what you're looking for, but it's more or less useless in your situation, while EasyFind's results tell you.
I never mess with files in locations that begin with /System, and neither should you or anyone else who's not an EXPERT; that part of the OS is "sacred."
You've got to judge which items can be safely deleted and which you should just grit your teeth and ignore, and if you'd like a little help in that respect, just post a screenshot of EasyFind's results.
I think I can say, though, that as a general rule, anything in /System is functional rather than invasive, i.e. not to be worried about.
