Is it possible to upload a whole folder instead of multiple files using Javascript?

Question

Is it possible to upload a whole folder instead of multiple files using Javascript? If so, what is the approach. If there is no straighforward approach, is there any workaround to achieve the same? I have always been curious about this topic. Any insights will help.

Answer 1

No you can't, except if its zipped, or you can use flash, silverlight or applet for uploading more than one file in the same time.

Edit:
For sure uploading multiple files at the same time is available now using html5 https://stackoverflow.com/search?q=multiple+file+upload+html5

Answer 2

EDIT

Turns out this is supported in Chrome 11, and seems to also work on Firefox if you use a vendor prefix: https://stackoverflow.com/a/5849341/486547

This is definitely possible with a Java applet, however the % of folks with a JRE installed has gotten pretty low these days (< 70%)

Google Drive does this (choose upload, then "Folder..") It works for me (Mac OS X 10.7.5 in Chrome).

I'm not entirely sure how yet. I'm working on a project where this matters, so I've been looking for a while. I'll update as soon as I have more.

Sounds like you're already aware of this, but in the mean time, you can use valums or blueimp to do multiple file upload.
