It doesn't matter if you are able to retrieve the original file location,
the browser won't use it. Allowing the server to pre-fill a FileInput field
is considered to dangerous -- if browsers allowed this then users could be
unwittingly tricked into uploading sensitive files by malicious servers.
Browsers require the user to manually select a file each time one is
uploaded.
