[Verizon] Seeing ALL folders when connected to pc?

[litobirdy]

How do you guys see all the folders on your windows pc?
I've seen mods where you have to do stuff to some files on your pc. And When i connect my nexus. I get all the standard folders, none of those system etc stuff. It comes up on my pc as media player. I have root explorer though so I can mod stuff directly on phone. But I was reading about skinning the soft buttons and I cant find a folder they talking about.

Here's the link in questions.

Anytime I do work on either systemUI.apk or framework-res.apk I will use root explorer to copy the app then paste it on the SD to get it to my CPU.

From there I will do the work I need to on the apk before pushing it back.

I like to do this with a rom so I can just replace the system apk within the rom zip prior to flashing but I believe it is possible to push it to /system using adb or fastboot.
