Question

I have an array with file paths (like “C:\…”) and I would like to open them with the default app, from my app. Let’s say it’s a list and when I click one of them, it opens.

This is the way to launch a file async:

await Windows.System.Launcher.LaunchFileAsync(fileToLaunch);

It requires a Windows.Storage.StorageFile type of file, which has a Path read-only property, so I cannot set the Path. How can I open them once they’re tapped/clicked?

Copied from my link in the comments:

// Path to the file in the app package to launch
   string exeFile = @"C:\Program Files (x86)\Steam\steamapps\common\Skyrim\TESV.exe";

   var file = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync(exeFile);

   if (file != null)
   {
      // Set the option to show the picker
      var options = new Windows.System.LauncherOptions();
      options.DisplayApplicationPicker = true;

      // Launch the retrieved file
      bool success = await Windows.System.Launcher.LaunchFileAsync(file, options);
      if (success)
      {
         // File launched
      }
      else
      {
         // File launch failed
      }
   }

You can of course omit the var options = **-Part so the ApplicationPicker doesn’t get opened

or you can use this:

StorageFile fileToLaunch = StorageFile.GetFileFromPathAsync(myFilePath);
await Windows.System.Launcher.LaunchFileAsync(fileToLaunch);
