It absolutely does not matter what kind of "file type" do you upload.
The simplest way to upload?
<html>
<body>
<form action="someURI" method="post" enctype="multipart/form-data">
<!--
<input type="file" name="file" id="file" /></br>
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
In HTTP request handled on the server side, you will identify the file data using the value of the attribute "name", in this case, "file".
