Access uploaded file by ID I have a webform that allows users to upload their CV/Resume's. The webform is sending me the file ID. I know that the URL for accessing those files is https:// example.com/sites/default/files/webform/myfilename. 

Can I access the file using the file ID instead of its name, for example https:// example.com/sites/default/files/webform?fileid=1502?
If you're looking to do this in code, I believe that this question has already been answered:

Given a File ID (fid) how can I get the HTML that represents that fid?

You can also access the file's page at yoursiteurl/file/fid, but this isn't a direct link to the file.
