Save with Other Extension in Notepad

Sometimes, we have to save in other extension from notepad, for example .ini; .inf. Default is .txt.
There are two ways to do this

First, if your setting allows you to view the extension, just rename it. For example from Extension.txt to Extension.ini.

Second, change directly when saving the file. In save as box dialog, you will see file name and file type. First, change the file type to All files, and then change the file name from *.txt to *.ini. For example Extension.ini
