How to move unity from C to D?

How do you move all the unity files from C to D without getting any error like "Could not find directory" or something like that? Is it just to drag and drop ?

And where is all the unity files located at? I want to move ALL the files!

help!!

 

Just uninstall it, then install on new location?

 

But am i going to loose all assets and games??

 

No, you will just uninstall Unity Engine, not your projects or assets.

 

So where/how do i uninstall it? And where does my games and assets save?

 

Oh man, you need to first learn some basics of using your OS. It depends on OS you are using.
Check this thread: http://forum.unity3d.com/threads/asset-store-download-folder.83620/
And where your projects are stored is about you.

 

When i uninstall it says: Do you wan to remove Unity and ALL OF ITS COMPONENTS?? If i understand that correctly it means that it will uninstall assets&games to!

 

WHERE THE HECCK IS UNITY?? I HAVE UNINSTALED UNITY AND BEFORE I INSTALLED IT I HAD 59 GIG LEFT, NOW WHEN I HAVE UNINSTALLED IT I HAVE 39?? WHERE IS THE REST OF THE FILES?

 

CAPSLOCK (also known as "shouting") won't help you.

Projects and Assets are normally stored in a different folder/location (e.g. Documents > Unity Project). Uninstalling the Unity Editor does NOT remove your Projects and/or Assets.

 

Now when i reinstalled unity and i choose D disk it still puts it in C i dont know whats wrong

 

Since you've written about C and D, I am going to assume you are using Windows.
Unity's default installation location is:
C:\Program Files\Unity
(unless you installed the 32-bit version, then it is Program Files (x86) instead).

However, that is not the only place Unity saves data. In addition to your project file(s), which you can save wherever you want, Unity also stores data in:
C:\Users\ *your account name* \AppData\Local\Unity\
C:\Users\ *your account name* \AppData\LocalLow\Unity\
C:\Users\ *your account name* \AppData\Roaming\Unity\

If I remember correctly, it is in Roaming Unity stores Asset Store packages etc which can take up a considerable amount of space.

Finally, Unity also has a Global Illumination cache folder. I can't remember it's default location (I think it is something like C:\GICache), but you can change it in Unity by going to Edit -> Preferences -> GI Cache.
