PerfectDisk Professional

What is PerfectDisk Professional?

PerfectDisk is a defragmentation utility for Windows that can optimize disk drives with an optimization strategy called SMARTPlacement as well as prevents fragmentation with OptiWrite (detects when Windows is going to fragment files and intelligently redirects I/O to stop the fragmentation).


The most used version is 14.0.890, with over 98% of all installations currently using this version. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The software installer includes 19 files and is usually about 40.87 MB (42,855,026 bytes). The program is built using the Nokia Qt cross-platforms native C++ framework.
