Prior to IE7 I was able to put a custom filename extension on a well known file type (like zip) and register that file extension to my application so that when it was downloaded it would be passed to my application by the OS. In IE7, either IE or the OS examines the contents of the file and decides to divert it to the application that is registered for the zip file type (in spite of the custom filename extension). Now (using IE7) the only way I have found to get around this problem is to make a minor modification of the zip file header so that IE7 (or the OS) does not recognize it as a zip file.
Is there any other way I can handle this???
