I actually set out and did some research and testing...turns out that opera seems to be the only browser that properly supports multi-file upload in a single upload widget. Safari definitely don't do it, and Firefox has the usability problem that it allows you to select multiple files, but only one end up in the widget (and get sent)..
didn't check IEwin yet, but I suppose this is reason enough not to use it in a real world scenario...which is a bit sad...
there is some discussion here: http://www.cs.tut.fi/~jkorpela/forms/file.html

Subject: Re: <x:inputFileUpload - How to upload multiple files at once?
I really don't think there is a possibility to use the standard <input type="file"/> to upload several files at once.
What gmail does is simply several <input type="file"/> boxes inserted dynamically with javascript.
you still have to click browse and select each file individually for each upload-box...
you can submit several files with one post though (using several file-upload fields, which again is what gmail does)

You can't use javascript to prompt for the files, unfortunately. If fact, if you re-post, that field blanks out.

The gmail one is still a lot of work for the end user because if they
want to upload multiple files they have to do so with separate "Browse"
buttons when it would be really nice to be able to select multiple files
at once.
I would love to have a MyFaces UI component for this, but I am not sure
how one would do this from the client end unless you could use
JavaScript to prompt for the files (sadly I am no JavaScript wiz).

Has anyone looked into how the Gmail "attach a file" link works? They
don't seem to display an <input type="file"> control (unless it's
heavily modified via css) and they let you attach an arbitrary number of
files fairly easily albeit with multiple invocations of the Choose File
dialog.
I suspect if there was any way to make the "Choose file" dialog select
multiple files in a single invocation then the gmail developers would
have done it.
The gmail file upload interface would make a nice JSF control if it is
not out there already.

Heath,
I'll debate that. I recall a Struts posting where someone made a
custom
class to detect and process multiple files in a SINGLE file upload
field.
But, we're not Struts, are we? LOL.

I don't think that the HTML element <input type="file"> supports multiple files. I think you can only select a single file.

theory, it is possible to do this (assuming I was reading the commons-fileupload documentation correctly) using an <input

However, if I remember correctly, the MyFaces component didn't look
like
it
supported that. If I remember correctly, it looked like it assumed
that
one
file was being uploaded. I never tested it with multiple files.

Do you mean using more than one <x:inputFileUpload /> or using a single <x:inputFileUpload />?
