What is PDAgent.exe?

PDAgent Module for PerfectDisk is a defragmentation utility for Windows published by Raxco Software.

PerfectDisk has the capability of a scheduled defrag managed by an internal task scheduler. It also offers the option to defrag during screen saver activity, or when the PC is idle.
