Okay, I went a little over the top on the title, but http://media-convert.com/ is a totally cool website.
I got an e-mail with an attachment in .wpd format --- an old WordPerfect file. I can't open WordPerfect files, and it's hard to find a way to do it.
I went to Media Convert, uploaded the file, and it converted it and allowed me to download the file in the format of my preference. Outstanding!!
