What is the best client side browser library to upload multiple files over http?

Question

What is the best client side http library to upload multiple files? If it can handle directories that\'s a huge bonus. I\'m looking for something that is open source or free

Answer 1

Another option that I have used before is uploading and then extracting ZIP files. I have used PEAR::Archive_Zip to extract. Requires more knowledge on the user's side, but supports directories and unlimited files (depending on the memory alloted to PHP).
