DragAndDropHandlers for Folder/Directory/Drive and AppInstaller

MVP

Although supported in the manifest, if a package contains desktop9:fileExplorerClassicDragDropContextMenuHandler for some of the non-standard file types (Folder, Directory, and Drive are known to show this behavior), these packages are bad and fail on installation.  Other file types seem supported.

 

Such a package will pass the manifest validation checking performed by MakeAppX, and even the initial check by AppInstaller, however once the package reaches 100% installed (visibly on the AppInstaller GUI), an error is then generated, and installation aborted.  The error states that the type (eg Folder) is not supported for system file associations.

 

An example of an application that could use such as association in WinZip.  The Microsoft MSIX Packaging tool does not add this entry by default, but the extension can be added to the manifest via other means.
