Oh Hush, He's learning. Just like I am and just like you did at one time.
You're right, and I didn't mean to come off as elitist. The desire to tinker should be encouraged - it is the driving force behind Open Source Software and Android.
But I still recommend the above poster learn more about file systems and computers in general, before he messes something up that he has no idea how to fix. Same for the guy who thought changing the view order in his file manager would help.
One of the best way to learn is by tinkering, but start with something that won't turn your expensive smart phone into an expensive brick. Get an old computer and install Ubuntu on it:
Desktop | Ubuntu It's actually the same underlying operating system as Android (Linux), so you can use some of the same commands and programs that you would use on your rooted phone, while learning firsthand how file systems, networking, users, and permissions work in Linux / Android.
There is a reason our phones don't come with root access by default - Motorola doesn't want to deal with warranty claims every time someone deletes the wrong file. If we encourage people who aren't sure what they are doing to root their phones, we are increasing the rate of these claims, which will lead Motorola to do even more to lock down their phones, which is bad news for everyone.
