I'm developing a site, and amajor part of the working with that site is uploading files to the site servers.
I have some third party softwares that deals with this uploading things just fine.
BUT in the browser, when the user clicks on the "Browse" button near the file field, he/she gets a browsing window from the operating system, but with filter "All Files (*.*)" and the combo box shows two more options "Pictures (*.jpg, *.gif)" & "HTML (*.htm, *.html).
How can control those filters? i.e. I want the user to upload only Access files (*.mdb), and I block, by javascript, the optin to upload file that doesn't end with .mdb, but I want the browse window to show him only mdb files?
a simple example to the form upload field is here:
<form action="DocumentNew.asp" ENCTYPE="multipart/form-da
file: <input type="file" name="filename" class="formtext" size="60">
<input type=submit>
</form>

Thanks for all your help everybody. It is good to see that things can be handled in mannerly way in EE. Zvika asked me for help and I tried to explain to him that "Not possible" is an answer sometimes. We agreed to reduce the points to 100 since the 200 points might be a little bit too high for that result. I will refund Zvika's remaining points and he will accept GreenGhost's comment (who was the first to point out the answer) as an answer.
I hope everybody will agree with that decision.

To my knowledge, this can't be done.
I have checked the MSDN reference for the input type="file" tag, and there is nothing there that suggests that the filters can be set in any way.
To accomplish this functionality, you would have to build your own file selector. That sounds like a little too much work for this little detail, though...
It looks like you have to educate your users instead. Add a text explaining what is expected from them.
