How many file types are you talking about? Maybe you can just create a list of types you want to support.

I can imagine these lists to be available on the internet as well, for instance

• here: http://www.webmaster-toolkit.com/mime-types.shtml
• here: http://webdesign.about.com/od/multimedia/a/mime-types-by-file-extension.htm
• here: List of ALL MimeTypes on the Planet, mapped to File Extensions?
• here: http://hul.harvard.edu/ois/systems/wax/wax-public-help/mimetypes.htm

Just get the file extension using ExtractFileExt and check it agains one of those lists. A file doesn't have a mime type in it, so you'll need to use either this list of file extensions, or determine the type by reading the file headers, which is harder and just as unreliable.
