I have a number of different applications that load the same file types, this is particularly true of graphic filetypes.
Most of the time I want my favoured application to load those particular file types, so I find it extremely irritating when another application decides to deal with that file type itself.
So having been frustrated for long enough (these magazine CD's with their own version of !ARCFS and a read only Fresco has been the final straw) I've finally managed to get round to do something about it.
Hence this module.
