Why is the value attribute not supported for <input type="file"> in modern browsers for security reasons?

The value attribute is not supported for <input type="file"> in modern browsers for security reasons because it could allow malicious websites to automatically upload files from the user's computer without their consent. To address this issue, you can use JavaScript to dynamically set the value of the file input field when needed, rather than relying on the value attribute. 

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;body&gt;

&lt;form action=&quot;upload.php&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;&gt;
  Select file to upload:
  &lt;input type=&quot;file&quot; id=&quot;fileInput&quot; name=&quot;fileInput&quot;&gt;
  &lt;input type=&quot;button&quot; value=&quot;Set File&quot; onclick=&quot;document.getElementById(&#039;fileInput&#039;).click()&quot;&gt;
  &lt;input type=&quot;submit&quot; value=&quot;Upload File&quot; name=&quot;submit&quot;&gt;
&lt;/form&gt;

&lt;/body&gt;
&lt;/html&gt;
