There is a website, which looks like:
Index of /2010/fall/lectures/ Name Last Modified Size Type Parent Directory/ - Directory 0/ 2011-Feb-15 12:35:17 - Directory 1/ 2011-Feb-15 12:12:35 - Directory 10/ 2011-Feb-15 11:42:48 - Directory 2/ 2011-Feb-15 12:12:39 - Directory 3/ 2011-Jun-18 10:48:50 - Directory 4/ 2011-Feb-15 12:12:44 - Directory 5/ 2011-Feb-15 12:12:46 - Directory 6/ 2011-Feb-15 12:12:48 - Directory 7/ 2011-Aug-01 23:07:15 - Directory 8/ 2011-Feb-15 12:12:52 - Directory 9/ 2011-Feb-15 11:42:49 - Directory
In each directory, there are some files.
I know in Firefox, there is "DownloadThemAll! Tools" that can download all files under current directory. But I don't know how to easily download files in each directory without manually clicking into each directory and then using the previous mentioned tool.
Also I only would like to download pdf and zip files, not those large mp3 and flv files. "DownloadThemAll! Tools" can achieve this by filters. But I don't know how to do this for files in each directory.
Thanks and regards!
