However, does anyone know where the "Film and TV" application can be accessed?
Right clicking on it just gives me other options, no "Properties" to check where it is located. This is a windows 10 related issue. I guess it is because the app comes from windows store or something.
The properties of the files can be found in the Tag
Action Window, or inline in the view if you are showing Details (columns) as opposed to Thumbnails or whatever. The [Filename] property contains the full path to the files. If you don't see [Filename] listed in the Tag Action Window, you can click the little menu button in the top-left corner of the Action Window and choose Show All Tags, and then it will show that listing.
If you want to locate a file in Windows Explorer, though, there is an easier way. Right click on the file and choose
Locate > On Disk (External). That will pop up a Windows Explorer window with the file in question selected.
As Arindelle mentioned, you can also use MC to send files directly to external applications using the Send To menu items. You can add your own applications, so you could send it directly to Windows Media Player if you add that application to the Send To applications.
