What is PDEngine.exe?

PDEngine Module for PerfectDisk is a defragmentation utility for Windows published by Raxco Software. PerfectDisk attempts to defragment drives in a single pass of a drive, as opposed to a common approach of running continuously and gradually defragmenting the file system. 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.

About PDEngine.exe (from Raxco Software)
