I'm using ShellExecute API to run an outside application(Acrobat Reader). Is there a way to put a faux file extention on my (.pdf) files to have my outside application (Acrobat Reader) to execute.

I have several reasons to do this, one of which is that if someone has Acrobat Exchange loaded, the (.pdf) files will open in that app. -You get the picture- I want to change my (.pdf)s to another extention name and have them be mapped to my outside app (Reader).

Any suggestions??
