Use alternative image viewer for multi-page TIFF

I'm having an issue with the built in viewer and multipage tiff images. It's fine if it doesn't support it (thought it really should), but what would be the best way to have them open with the Windows Photo Viewer which does handle multipage tiff images? Do I need to disable the built in viewer completely or can I have DO behaving differently for TIF images?

Thank you,
Adrian

Yes, you can do this by editing the filetype (Settings / File Types) double-click event to override the normal behaviour.


NM, I just disabled the internal picture viewer option under Preferences->File Operations->Double-click on Files. A check box was much easier than jumping through hoops trying to learn how to use the override behavior to deal with the Windows Photo Viewer which isn't a simple exe that you just point to. It runs under the Windows host process (Rundll32). If I find some time I'll read up on it, but right now I just needed it to work.

Thank you,

You don't need to worry about rundll32 etc, as shown in the screenshot the only command you would need is FileType ACTION=open. Up to you though.

Well, I tried, but can't figure out how to set the Left double-click event to FileType ACTION=open. I looked everywhere and I don't see that as any option I can configure. This is what I did and maybe you can see what I'm doing wrong.

In DO, under Settings menu I opened File Types.
In the File Types dialog, the extensions are grouped into 3 sections, Directory Opus File Types, File Type groups and System File Types. I expanded System File Types and located the TIF extension.
Once selected, I clicked the Edit button on the bottom right corner which opens a dialog "Edit 'TIF File' File Type"
There's a tab control with Actions, Events, Context Menu, and Drop Menu.
I selected the Events tab which is what you showed on your screenshot.
I selected the "Left double-click" item and then clicked the Edit button.
This is where I get lost.

I see 5 menu items, Edit, Commands, Arguments, Browse, and Modifiers.
At this point I'm assuming I should be looking in Commands, but I checked them all. Nowhere do I see anything that says ACTION or open.

Thank you,
Adrian

Just paste the command Jon gave ( FileType ACTION=open ) into the box:


The command is FileType, while ACTION is one of the arguments to the FileType command. But you don't need to use the menus; just paste the command in like in my screenshot.
