Safari on Windows has a bug and reports a file size of 0 bytes when selecting multiple files. Selecting single files works.
It is possible to select a complete folder structure, though this is currently only supported by Google Chrome.
To enable this feature, the following vendor-specific directory attributes have to be added to the file input field:
<input type="file" name="files[]" multiple directory webkitdirectory mozdirectory>The following browsers support drag & drop:

Depending on the size of the file, the operating system platform and the network throughput, the number of progress events triggered might differ.
e.g. Google Chrome might only trigger one progress event for the upload of a 100KB file on Windows XP, but trigger multiple progress events for the same file on Windows 7 and Mac OSX (tested with Google Chrome version 22).
Please also note that some programs that analyze network traffic are known to interfere with the number of progress events triggered, e.g. Web Debugging Proxies or Firewall/Antivirus software.
