Opening a file in a Metro app from command line

I need a way to open a file in a Metro app from command line.

So far I've figured out how to start the app from command line without any third-party scripts

explorer shell:AppsFolder\Microsoft.Reader_8wekyb3d8bbwe!Microsoft.Reader

but I haven't been able to figure out how to include a file name yet.

Launching

explorer shell:AppsFolder\Microsoft.Reader_8wekyb3d8bbwe!Microsoft.Reader example.pdf

just opens up a default explorer window.

Any idea from Windows 8 experts on how to accomplish this without any third-party tools/cmdlets/etc.?

Note: In fact I'm using Windows 10 but I guess if there's a Windows 8 / 8.1 way to do it, it'll work for 10, too.

The best way I've found to pass command-line arguments to the executable targeted by the shell command is via the Windows start command.

Using your example, you would end up with this:

start "" shell:AppsFolder\Microsoft.Reader_8wekyb3d8bbwe!Microsoft.Reader example.pdf

I don't have Microsoft.Reader installed, so I can't test that. However, I can verify that this pattern works with Windows Terminal. In this case, I pass it a command-line argument to tell it which profile I want to open.

start "" shell:AppsFolder\Microsoft.WindowsTerminal_8wekyb3d8bbwe!App new-tab -p "GitBash"

The first argument to the start command here — the empty string — is just the title of the window.

You can also pair this with cmd /c, which I've found is necessary for some launcher applications, such as my personal favorite, SlickRun:

cmd /c start "" shell:AppsFolder\Microsoft.WindowsTerminal_8wekyb3d8bbwe!App new-tab -p "GitBash"

I have a blog post with more info on running Modern apps from the command line, which you might find helpful in constructing these ridiculously obtuse commands.

Not sure if it works on Windows 8, but on Windows 10 I use this:

cmd /C start <app-name>:

For example, to start Slack:

cmd /C start slack:

Store Apps can only be started by the shell. So try this:

explorer.exe shell:AppsFolder\Microsoft.WindowsAlarms_8wekyb3d8bbwe!App

Or from run (Win+R):

shell:AppsFolder\Microsoft.WindowsAlarms_8wekyb3d8bbwe!App

If you're still looking for the answer, the best way to open a file in a metro app is to use an execution string like a normal app protocol does. The execution string looks like this:

bingnews:[arguments, can be left blank.]
microsoftvideo:[arguments, can be left blank.]
netflix:[arguments, can be left blank.]

So, to start up netflix, it's as simple as typing in Start netflix: into the command line.

To find the execution string for an app, go here: Control Panel\Programs\Default Programs\Set Associations

More info and examples can be found here.

http://www.itsjustwhatever.com/2012/10/28/launch-windows-8-metro-apps-from-a-desktop-shortcut-or-command-line/

PLEASE NOTE: To open an app WITHOUT A PROTOCOL (One not listed in the registry or under "Set Associations") use OP's method:

explorer shell:AppsFolder\[appuid]![appfullname]

The app UID is the folder name without the version number. For example,

4DF9E0F8.Netflix_2.11.0.8_x64__mcm4njqhnhss8

becomes

4DF9E0F8.Netflix_mcm4njqhnhss8

The app fullname is the [App author].[App name] For example, 4DF9E0F8.Netflix. 4DF9E0F8 is the author, and Netflix is the name.

Put it all together to get

explorer shell:AppsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!4DF9E0F8.Netflix

If the app is the default handler then you can just launch the file or protocol. There isn't a good in-box way to launch a file into a non-default handler from the command line.

Windows Store apps aren't designed to run from the command line and there isn't a straightforward way to launch them from the command line. Apps which handle specific files or protocols receive them through FileActivatedEventArgs or ProtocolActivatedEventArgs rather than command line arguments

You could write a launcher app which uses CLSID_ApplicationActivationManager's IApplicationActivationManager to ActivateForFile a specific app.
