As described in the section „Presentations“ you can fetch a list of all uploaded documents. Each document has all information about a unique files Id, name, download URL, the conversion status and the event (see „Types of Variables“ -> Files-Object). With this information you can create one page per event and provide the documents.
Also you can store in your own database which files (base on the file id) are downloadable by normal users.
