I thought it was doable. However, after looking into it I've learned that the API for this is quite limited. For Microsoft Store apps, context-menu entries are only shown if the app is the default for the given file extension. This means that if I would add support for that, Mp3tag needs to be set as the default app for, e.g., `*.mp3` files — and I think this is a little bit over the top. While I certainly love my app, I think the default app for any given audio file should be the player. I've cast my vote at this [Windows Developer UserVoice proposal](https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/35467633-allow-context-menu-verbs-with-file-explorer-integr) and hope that this will be improved with a future version of Windows. Till then, I'll probably continue collecting negative ratings on the Microsoft Store due to missing support for the Explorer context-menu. --- _[View the full topic](https://community.mp3tag.de/t/win10-store-app-does-not-add-explorer-extension/42775)._
