Well, Photoshop is moderately complex when it comes to opening
files. It gives you the option of specifying a specific type, all
readable types, or all files. If you select 'all files', it will
attempt to open any file you select, and only after trying to open it
will it indicate the file is not a valid image file.
Word acts the same way.
All I'm saying (and I'm not the only one) is that the only way to be
sure your user has selected a file your application can handle is to
check the file for the formatting your application expects and report
success (continue processing) or failure (tell the user the file
selection is invalid).
You can set your filter up any way you want, but even that isn't
going to prevent a user from changing the extension or the file type
of an 'invalid' file so that it appears valid.

It looks that you meaning in PhotoShop you could select an .html
file, but you can't, so your text is misleading, and perhaps thats
the meaning. (Checked in Photoshop CS)
