Windows 7: How do I set a certain file type to open with certain program

I used to be able to open replays of a certain game (Warcraft 3) just by simply double clicking on them. I reinstalled Windows 7 2weeks ago, along with the game. Now when I double click them, it doesnt know what program to use --> I go through the standard "open with" and find my war3.exe. Now when I go to double click the replay file, it openes warcraft3 not the replay itself (like it used to, and like how I want it).

Ive done alot of digging around and trying to find how to fix it, but Im still unable to fix this. What I've found out that I basically need the replay files (.w3g) to open in

E:\Program files\Warcraft III\war3.exe -loadfile "%1"

The problem is, that with windows7 I am unable to find the place where I can insert this, all I was able to find was ways for XP/Vista but they are different from Windows 7.



So I would be very glad if I could get some help, will give more details if needed.

Hello,

There are a few recommendations on here:

Tried that, doesnt help me. What I need is exactly what I described in my first post = .w3g files to open as E:\Program files\Warcraft III\war3.exe -loadfile "%1"

You can create a script and convert it to a Executable.
