resource requirements

The disk space requirements for Diskeeper depend on several factors. The Diskeeper installation package is about 60 MB. After the installation is complete, Diskeeper occupies about 38 MB of disk space. If Internet Explorer is not present on your computer, some other needed files (hhupd.exe, 50comupd.exe, and wintdist.exe) may be added. Further, your system may require a new or updated version of the Microsoft Management Console (MMC), which is less than 6 MB.


additional software requirements

Diskeeper relies on the Microsoft Management Console (MMC). The MMC provides a single point of control for system utilities such as Diskeeper. The MMC is used as a central location for a variety of Microsoft and third party administrative tools. The MMC is included in Microsoft Windows 2000 and newer operating systems.


a note about firewalls

As a normal part of its operation, the Diskeeper Service (DkService.exe) acts as a server on your system. If you are running a hardware or software firewall, you may see messages indicating Diskeeper Service is trying to act as a server. These messages are expected; you can safely allow these events. This functionality is designed to allow for support for network operations (e.g. Remote Control) via Diskeeper Administrator.

You may also be notified that Diskeeper is trying to access the Internet. It is important to note that Diskeeper does not access the Internet (except when you specifically use the Check for Updates feature), but it does use Windows mechanisms that may trigger these alerts from your firewall. Again, these messages are expected and you can safely allow the events. If networkability or automatic update checking is not required, you can safely disable this.
