The dialog box is displayed by the browser when the user clikcs on the Browse button. Not all browsers behave in the same way in this case. Some older browsers do not even display the Browse button, forcing the user to enter the full path name of the file being uploaded.

I don't think you can control the options in the dialog box from a CGI script or using any HTML code.

One think you can do is read the file name first and check the extension if it is the wanted one and display an error page it its not.

$fileName = $myCGI->param('fileName');
if (!$fileName) {
    print $myCGI->p("Sorry, your submission didn't include an upload.");
} elsif ($fileName !~ m/\.txt$/i) {  # check the extension
    print $myCGI->p("Sorry, Only text files are accepted.");
} else {

# process the upload

}
