Open any file in app
We have a lot of third party apps for handling pdf, images, blueprints etc. It should be simple to open the file from Teams or SharePoint directly using Open in app. Then it should open the file in associated app in your computer, in the same way as when you have it in File Explorer (that could be your synchronized OneDrive or an SPO site). Now we have to synchronize everything, to be able to use appropriate app from File Explorer.
This would be awesome. With such a function we would be able to use all files in SharePoint/Teams. Today we need to download third party files (for example CAD), edit and upload again. Thats not an easy and user friendly flow.
