var estremi = new Array();
var entrata = new String;
var msg = new String;
entrata = document.fs.File1.value
estremi = entrata.split["-"];
msg = "E\' corretto questo anno? \n" + estremi[0];
//all we have to do is return the return value of the confirm()
method
return confirm(msg);
}

deprecated, use:

<script type='text/javascript'>

you do not need new Array(),
as it will be reassigned by split() anyway

> var entrata = new String;
> var msg = new String;

new String not needed, use:

var estremi,entrata, msg

> entrata = document.fs.File1.value

more complete and versatile:

entrata = document.forms['fs'].elements['File1'].value

> estremi = entrata.split["-"];

This [] is your ERROR, use:

estremi = entrata.split("-");

> msg = "E\' corretto questo anno? \n" + estremi[0];

Escaping the ' is not necessaty, do:

msg = "E' corretto questo anno?\n'" + estremi[0] + "'";

Try:

<script type='text/javascript'>
function verify(theForm){
var estremi,entrata, msg;
entrata = theForm.elements['File1'].value;
estremi = entrata.split('-');
msg = "E' corretto questo anno?\n'" + estremi[0] + "'";
return confirm(msg);
};
</script>

<FORM method='post' encType='multipart/form-data'
action='ToFileSystem.asp' onsubmit= 'return verify(this);'>
<INPUT type='File' name='File1'>
<INPUT type='Submit' value='Upload'>
</FORM>

Thank you!
I used the name of the form and not "This". Mysterious javascript ;-)

estremi = entrata.split("-");

split is a function, thus you must use "(" and ")", not
square brackets "[" and "]".
