Here's something that I've been pondering for a while, and met no success in the Technet forums. In the past, I've tried setting up a content type for both .PSD and .SWF, so that rather than having to reopen continual file templates for design projects then having to save/upload time and again, I can load one up from the New menu.
Didn't work, on the basis that SharePoint didn't recognised a SharePoint Services compatible application when the call was made to Flash / Photoshop respectively.
Now, as best I can see it, the SharePoint association between file and application for Content Type purposes is dictated by ActiveX controllers, but I'm unable to find anything more than that.
So, my question is, how does one go about making Content Types with non-MS file types?
