Loading an offline .HTML file saved from my computer

So I downloaded a web page that I would like to browse offline. It has java in it and lots of images, etc. I copied it all over to my SD card and in theory when I open the page up it should load the offline version of the web page (It works on my windows phone). But on Android it's refusing to load any of the java script stuff.. and also it's taking me to content://0@media/external/file/1234 . That seems like an odd filepath. It should just be D://folder//webpage.html but I have no idea how to make it work like that.
