I'm really interested in how to open this file. I have huge Safari history. Last year, I followed classes in a foreign country, and had an e-class system with all my projects, classes supports... I cannot access to the e-class specific web pages from my login page (which I still have access to). But I figured accessing it through the web page by the History URL opens to the exact files, and even video recordings, exactly what I'm looking for. I'd like to filter my history with those criteria, and be able to recover all my classes, which were very interesting :)
