Batch: Open a specific file in a specific program?

Question

How do i tell windows to open C:\test\test.txt in WordPad, when Notepad is my default program for .txt files?

Answer 1

The accepted answer didn't work for me. I am not sure if it was because of the program I was trying to run, or because the path had spaces in (even though I wrapped it in quotes), or something else.

Anyway, I was able to do it be adding an empty string after the start command.

For example:

start "" "C:\My Programs\myprogram.exe" "C:\My Files\myfile.txt"

Answer 2

You can add the direct path to the executable like

start C:\Windows\System32\write.exe [FILE]
