yes. the giggly php manual has a good section on file uploading
http://php.net/features.file-upload

if php isn't you giggly language just translate what it says into your
language or check your languages manual.

excellent forms reference:

yes, see the above. just never forget where it mentions on the form the
max file size evil people can change it and make you cry.

thanks for help

I did a quick google search and found this code. I think it will only
work on windows, in Internet Explorer

<html>
<head>
<script language="JavaScript">
function A()
{
var oas = new ActiveXObject("Scripting.FileSystemObject");
var d = document.a.b.value;
var e = oas.getFile(d);
var f = e.size;
alert(f + " bytes");
}
</script>
</head>
<body>
<form name="a">
<input type="file" name="b">
<input type="button" name="c" value="SIZE" onClick="A();">
</form>
</body>
</html>

There are many links here -

one gets you there:
http://www.htmlhelp.com/faq/html/forms.html#file-upload
.... but no word about restriction here.

another one:

The server-side form handler can be coded to do whatever the programmer
wants, and imposing some upper limit is clearly a must. (That is, the code
should check for the input size, and discard, or otherwise process in a
special way, submissions exceeding a reasonable limit.)

.... but how?

And I wouldn't restrict 'restriction' to forms.
What about ftp upload?
