Folder.HTT in Windows 98 SE

I want to edit Folder.HTT in C:\Windows\Web to be able to view media files in Windows Explorer (in the left pane of a folder). I have already changed some of the text in this file from "Var Want Media = false" to Var "Want Media = true". Now I can play almost all media files with a mini Windows Media Player in the left pane of the folder. However, Windows Media Player does not play files with the extension .MOV. How can I get a QuickTime Player to pop up in the left pane of the folder for these file types? What text do I have to enter in the file Folder.HTT to allow this? Thanks in advance!
