Where is system/library/extensions in OSX 10.10? so I am now using vmware player to mount the osx now, and since I accidentally installed the svga display driver with the vmware tool one from darwin now I cant change the resolution of it so I need to uninstall the svga. I try to find system/library/extensions so that I can uninstall the svga driver but I cant find it in the library. Where can I find it or it is just hidden in the library folder?
⌘-Shift-G is the hotkey for the "Go to Folder" dropdown menu. Just type in /System/Library/Extensions and click Go to open that folder.

P.S. I think your screenshot may be in your User folder, not the System folder. The System folder lives in Macintosh HD, not within a specific user's files.
