How to link to a form to change an uploaded file

Hello,
I have created a form where a user can upload a file.
What I now would like to do is list those files in an HTML view and provide a link to go to that file's form to change the file.

It's simple to show a list of all the files from the form, but I don't see how to create a hyperlink to that form for a specific file.
I have tried with using the filename as a parameter but that didn't work.
Hope someone has a suggestion
Rob
