FileChucker is helping drive the backend of several high profile entertainment sites for people like Shania Twain and Dolly Parton.  We're also using it to drive backend file uploads for a multi-billion dollar banking institution.  It's a great product.  We've tried other "chucking" upload solutions with progress bars using flash and php, but nothing works as reliably as FileChucker.

FileChucker is a great drop-in solution for file uploads, and worth every penny of its very reasonable cost.  Encodable's support is excellent to boot.

The amount of customization in the program is incredible.  I was able to integrate it into my existing page layout relatively simply.  I was also able to easily customize the look/feel to match the current site.
