Great Importance!!! Please pay a lot on this notice!!!

Note that the path can neither contain chinese words nor special character
It can only contain digit, english letter and '_'
 
I recommend that the principle of naming your path is same as the principle of naming variables in C++.

Step2: Build a project in Unity

The build project must be the subfolder of Packages in your project path.
i.e. <your project path>/Packages

When I don't select the correct path (for me, path is C:\UnityProject\PhoneTest\UnityPhoneTest8\Packages), I can not build a project successfully. The error message such as "Invalid build path: c:/unityproject/phonetest/unityphonetest8/projectsettings" will occurs.

The path of build project can not contain chinese word or special word.
It can only contains english letter or digit or '_ '.


When my path of build project contains chinese word, The error message such as "invalid build path" will occur.

Path name about Desktop.

Although you rename "桌面" as "desktop" in Windows Manager,
Unity also recognize it as "桌面" instead of "desktop" that I expected.
So I recommend that  when you create a new Unity project, don't select the location under "desktop" or "桌面".

But... . I created a new Unity project which location was under "desktop" at beginning. What did I do?
I just moved the Unity Project in C:\UnityProject\PhoneTest.

But ... .When I moved some file from "desktop". I encountered an annoying issue. A window was popped up saying my file was opened, can not move it.
I think I did not open files, even though I closed all files, apps and folder windows. I can not solve this issue.

To reader, have you experienced the same problem. Do you think it is odd.
I thought it is odd before. After when I googled it for answer last night, I don't think it is odd anymore.
It may often be caused by thumbnail.db file.

Just close all files, apps and folder window. Then delete permanently about thumbs.db file (all start with "thumbcache" and "iconcache" ) as many as possible. After deleting it, it just left fewer than files.
Remeber that don't let system automatically generate about thumbnail.db file.
