An introduction to Windows CMD batch scripting, including file association tips.
Creating File Associations
You can create file associations in Windows CMD by using the following commands:
Assoc .php=phpfile
Ftype phpfile="C:\Program Files (x86)\Notepad++\notepad++.exe" %1

Tips
When renaming a folder, you can press and hold Alt while typing 255 on the numeric keypad, then press Enter. Note that this only works with the numeric keypad, not the numbers at the top of your keyboard.
