Many eons ago, old Windows applications used a .pif "Program Information File" although I don't believe it has been in use since Win95????

When I first got my hotmail account, I attempted to figure out a way to block all of the smut, and learned that virtually ALL SPAM comes in with phony "From" info.

A file that comes in with an "extension" registered on your machine will usually behave as you intend it to. A...H... who want to do something to you may look for an innocent looking extension that won't be registered, and of course if it's intended for use by something they sent, they can use any extension they want.

Delete.
