<INPUT TYPE = "FILE"> tag

I'm stumped. I am trying to figure out how to place a default value inside of this tag. I tried all attributes for the file type tag and none of them work. 
 
I assumed that if I have the following tag: 
 
<INPUT TYPE = "FILE" VALUE="valuegoeshere> 
 
Then there will be a default value of 'valuegoeshere' so I won't have to always select the browse button. 
 
Am I doing something wrong?hmmmn, interesting. I also cannot 'insert' a value into the field. Makes me think that it is a browser secutity setting... especially since you don't have the right to browse the users pc. 
 
I can validate the field though.... 
 
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
 
<html> 
<head> 
<title>Untitled</title> 
<script langauge=javascript> 
function check(){ 
if (document.form1.file.value==''){ 
alert('empty!'); 
}else{ 
alert('full'); 
} 
} 
</script> 
</head> 
 
<body> 
<form name=form1> 
<input type=file name=file> <input type=button value=Submit onClick="check()"> 
</form> 
 
 
</body> 
</html>It's a security thing - otherwise sneaky *******s would populate it with a nasty file name. 
According to MSDN, the value property is read-only.

how would you know what the value is if you don't click on browse?? 
 
just curiousAs has already been stated. It is read only. If it was not then a 
site could steal files from a users computer. The best you can 
do is suggest what the user should put in, and then filter the entry. 
 
That is why I use filtering like this: 
 
<head> 
<title> file type filter </title> 
<style> 
body {background-color:blue;color:lightyellow} 
h1 {background-color:lightsalmon;color:seashell} 
#prompt {padding:10;background-color:blueviolet;color:floralwhite; 
width:250} 
.container {width:250;background-color:brown;color

eru; 
border:3px outset burlywood} 
.file {background-color:deepskyblue;colorcadet:blue; 
border-color:lightsteelblue} 
.sbutton {background-color:dimgray;color

ink;border-color:dodgerblue} 
</style> 
 
 
<script language="JavaScript"> 
 
</script> 
</head> 
<body> 
<h1 align="center"> File Upload Filter</h1> 
 With this script you can set the file extensions that are acceptable 
for uploading and the user will be prompted with the list. When 
they select a file and submit, the extention will be validated and 
either the submit will be executed for the user will get an alert. 
 
 
<div align="center"> 
<script language="JavaScript"> 
 
</script> 
<div align="center" class="container"> 
<form method="post" name="myform"> 
<input type="file" name="myfile" class="file"> 
 
<input type="button" name="Submit" value="Submit" class="sbutton" 
onFocus="this.blur()" 
onClick="filterFiles(document.myform,document.myform.myfile.value);return false"> 
</form> 
</div> 
</div> 
</body> 
</html>

<INPUT TYPE = "FILE"> tag
