Add or edit model in LTspice

Find this directory of LTspice on your computer, choose lib folder, then cmp
I found it in the direction below:

C:\Program Files (x86)\LTC\LTspiceIV\lib\cmp

In folder cmp you will see these files which is the information of each components.

Use text editor such as notepad++ under administration mode to edit the file.

Or you can copy mine and paste it in the same folder
