I've copied a lot of reference books in HTML format (Not PDF) into the /download/directory of my G1's SD card. Does any one know the URL path for the memory card so that I may read the files with the browser? I've tried file:///disk/download/myindex.html, file:///download/myindex.html, and file:///sd-card/download/myindex.html, all much to no avail. What am I doing wrong?
