.nib files lost

Hi everybody
After running CleanmyMac software some systems files of some apps were lost
I found some and most of the missing online but still i am looking for:

1/ Information System.app

2/ Automator.app

3/ Grab.app

4/ X11.app

I need the .nib files situated on Resources folders that are found after right clicking the application and open Package Contents
Need to be OS Yosemite
If somebody can send me this or post it online it will be great coz i don't want to reinstall all System
I didn't back up what i know i should have done but........

Thanks

 

You seems very smart and i am sure you never made or never will make any mistake.....and by the way,thanks for giving me those files i ask for.....
