Get applications to open a given file (Mac and, or Windows)

Under Linux/Unix I use GIO (pygobject) or gnome-vfs-python to get a list of installed applications that can open given file (for example image in graphics software). Is there something that can be used for MS Windows or Mac OS X? -- http://mail.python.org/mailman/listinfo/python-list

Desktop/File management support on MS Windows

Are there any Python libraries that can trash files (move to Trash, not delete) or for example return a list of applications that can open given file? I can't find anything related to this for Windows. -- http://mail.python.org/mailman/listinfo/python-list
