jupyter notebook home path changing - %USERFROFILE% and Configure file
如何改变jupyter notebook默认初始文件路径，网上都提供了很多方法。Link1 , Link2
但他们都没让你这样测试：
[Win] + R , "cmd", 在windows命令行运行：
C:/ProgramData/Anaconda3/python.exe C:/ProgramData/Anaconda3/Scripts/jupyter-notebook-script.py
注：如果这样测试可以修改，而通过开始菜单双击“Jupyter Notebook”快捷方式还是没改过来，那就往下看。
他们都忽略了一个问题：在 Jupyter Notebook 快捷方式 - 属性 - Shortcut Tag- Target 栏内的内容，会影响你修改的效果。
即：可能你已经改了以下文件：
- C:Users<username>.jupyterjupyter_notebook_config.py
- 并把快捷方式里Start In内改成了你要的path: C:Users<username><your_preferred_path>
还是可能不生效，原因就是 Target 里的%USERFROFILE%或别的内容在使改动不生效。
我的Target内内容：
"C:/ProgramData/Anaconda3/python.exe" "C:/ProgramData/Anaconda3/Scripts/jupyter-notebook-script.py"

Nov 2, 2017 Updated:
1. Install Anaconda 5
2. add the path of "jupyter notebook.exe" into Environment Varialble: "path"
make sure you can launch jupyter notebook by: launching cmd command: "jupyter notebook"
3. in cmd window, cd to the path that you want to create the configure file "jupyter_notebook_config.py"
you will get: Writing default config to: C:UsersAdministrator.jupyterjupyter_notebook_config.py"
4. modify the config file "jupyter_notebook_config.py" at line of "#c.NotebookApp.notebook_dir ='' "
as:
c.NotebookApp.notebook_dir = '<path you prefer>'
5. now you can launch jupyter notebook via cmd window. But, the shortcut is still not like you want.

6. modify the content in "target" in your properties of your jupyter_notebook's shortcut:
"C:/ProgramData/Anaconda3/python.exe" "C:/ProgramData/Anaconda3/Scripts/jupyter-notebook-script.py"
OK.
