Disk Monitor is an application that monitors your computer's local drives. It shows free, used and available disk space, disk capacity and additional drive info. DiskMonitor provides several notification methods - you can choose to be announced by a message box or an alert sound. DiskMonitor can also open an external application or append to a log when the condition you enter is matched. If you're away from your computer, you can choose to receive an e-mail or a net message. You can specify minimum or maximum free/occupied space values as triggers for notifications
