1. Clean and lean user interface

3. Flexible methods to specify save paths
4. Regular expression support
5. Group applications by user defined categories
6. XML based import/export of applications
7. Run custom commands after downloading
8. Online database

How does it work?
Basically, it monitors the content of web pages for changes and downloads files to a specified location. There is a tutorial explaining it all. Currently, you can either rely on a service based on FileHippo, or you can define your own rules, even using regular expressions (for advanced users). A similar application, for monitoring web pages, is Webmon and has sometimes served as guide.

The license of this software is Freeware, you can free download and free use this system maintenance software.
