Declaring file types you want your application to be able to see

In Solution Explorer open Package.appxmanifest > Declarations > File Type Associations

In Properties > Name, give this declaration section a name. E.g. “resource_files”

Then in the Supported file type section

  • Content type: can be blank
  • File Type: the file extentions (e.g. “.mp3”)

Add as many as needed
