Prevent HTML file field from being delete after PHP validation roundtrip [duplicate]

Question

I have a HTML file field <input name="File" id="FileName" type="file"/>. When I submit the form, I do receive the file, all fine. However, when I validate the user's input and cannot accept the values provided, I will need another round trip. As usual, I will redisplay the form plus error messages.

For text field or textarea I can set the (already) provided value, e.g. by value or just echo the value in the textarea. How could I do the same for file fields? I want to avoid that the user always has to reselect the file in the browser.

This is not possible - you have to store the file on the server to do this. Then you can show the user a short info about the already stored file and the option to upload a new file or delete the file

Yep, seems to be right, was trying to store the path via Js, but even this failes: onChange= "alert( document.getElementById('FileName').value );" does provide a fake path, not the original upload path.
