2. NOK, cannot longer create Shortcut, Bitmap, Textdoc, Zip-File and Folder icon changed:
the same issue in Windows Explorer
It's standard folder background context menu that is populated by the Shell. JM doesn't change this menu. As you can see, Explorer displays the same New submenu.
On Windows 7, New submenu is the same for the long paths, but commands produce "Destination Path To Long" error.
OK, so it seems the issue is caused by the long file name. Anyway, I would expect JM to throw an error message:
