A File Upload/Download Control/Component by Aurigma Inc.

File Downloader™ has a range of features that can be appreciated at its true worth by creators of online file storage systems – possibility to preserve folder structure, appearance customizability, localization support, rich client-side API, and others. It can be used with any server platform, such as ASP.NET, PHP, ASP, and others.

Now you can forget about clumsy download solutions as ZIP files, standalone download applications, or (even worse) a set of links for each file. User-friendly mass download becomes reality, not a dream.

How Does It Work
Assume that you have online file gallery, and this gallery allows a user to mark files as favorite. The user may want to download all files from favorites. This is where File Downloader™ aids.

You put File Downloader™ to your HTML page. It looks like a common button. When the user clicks this button, File Downloader™ gets a list of files to download from your application. The user selects a folder on their computer where to save files. After that the download begins and the user sees a progress bar. If necessary they can skip certain files. When download completes, the user can see the log and therefore they become aware if anything went wrong.

End-User Features
- Resume interrupted downloads.
- Possibility for the users to select any folder on their computer.
