Add to the list of ''Open with'' programs?

[JeromeR]

I'd like to right-click and Open with using an application that's not listed.
• From within Flare, open an .htm file by using Notepad++.
• From within Flare, open a .css file by using TopStyle Lite.

How do I add these applications to the respective Open with right-click menus? …or is there another few-clicks way?

Note that, in this work environment, I cannot run RegEdit but I have limited Admin rights to install software.

Thanks in advance.

The only way I've been able to do it is to set the desired program as the default for the file type in Windows. For example, I like to use Nopepad++ for stylesheets, so here's how I set it up:

1. In Windows Explorer, right-click any .css file, selected Open with > Choose default program. The Open with dialog displays.
2. The Always use the selected program to open this kind of file box must be checked. Click Browse. A second Open with dialog displays.
3. Go to Program Files (x86) > Notepad++ and select Notepad++.exe.

Since this impacts all files of this type, it may not be ideal for your situation since all .htm files outside of Flare will open in Notepad++ if double-clicked.

Kwag is right, the open with command uses the programs registered for the file type (extension) in Windows.

Once you've opened the file type in Windows using your preferred program it should be in the list. It might require a restart.

You do not need to make the program the default, just opening the file type with it should register it.

I'd forgotten the solution but I remembered asking this question before. Your responses are still useful. Thanks.
