Ever since I released the blogdrive downloader using WGET sometime an year back, I have also been receiving steadfast requests for a cross-platform version of the same because WGET is a linux tool and Windows PHP can not make use of the same unless you have some tricky combinations of Cygwin and other tools.
Today I got some time and wrote a quick version of the same using native PHP fopen/fwrite for the benefit of users. It uses a simple jquery to do an AJAX request and keeps saving the file onto a subfolder on the server.

- CAPTCHA security when using this on a hosted platform.
- Use Jquery from a CDN instead of having a local version of the script.
