Disk Watchman

Disk Watchman is a Windows application that monitors your hard, removable and mapped network drive resources. It displays free and used disk space on a real-time basis. You will be able to see when your free disk space falls short of certain values.
Disk Watchman contains rapid tools to find disk space reserves (backup, temporary and duplicated files.) You will be able to free up more space effectively with its intuitive and fast user interface.
Furthermore, you can receive notifications about low disk space, even when you`re away from your computer. You can choose to be notified by e-mail, sound or other options. Now you can start any application that consumes disk space actively and be confident that you know what is going on with your computer.
Some common examples are - Web site downloading, audio/video capturing, active usage of file/database/web server resources, etc.
Using an E-mail to SMS gateway you can receive disk space notifications to your mobile phone as well.
Advanced users will be pleased with the ability to monitor file system changes. You can record filesystem state and then make a comparison report to see which files have been added, removed or changed.
Disk Watchman provides a simple and comfortable user interface, easy to understand setup and full control over the visualization process.
