IObit Smart Defrag 3.1
http://www.iobit.com/iobitsmartdefrag.html


Smart Defrag 3 is a free, light, and stable disk defragment tool designed for maximum hard drive performance. Based on IObit latest disk defrag engine and "Boot Time Disk Defrag" technology, Smart Defrag 3 not only provides defragmentation, like any typical disk defragmenter can do, but also intelligently streamlines your files based on using frequency, thus accelerating disk speed for faster data access! With the unique Deep Analyze technology, it smartly clean junk files before defragmentation to save more disk space for you. Being the first Disk Defragmenter that fully supports Windows 8/8.1 Metro Apps, Smart Defrag 3 works fast, automatically and quietly in the background and is a disk defragmenter suitable for large hard drives.​

  • Improved GUI
  • Added and improved multi-language pack
  • Fixed bugs

"Day 0" - Installed on 2 PCs running Windows 8.1 Update 1 (HDD only). Did the whole clean sweep; Boot Defrag, Deep Analysis, Defrag and Optimise/Prioritise including for Metro/Store Apps. Took many hours.

Tomorrow I shall see how these systems are running, and post my findings for "Post-SD3.1 Day 1".

Forgot to update my reply, no noticeable improvements to performance. Uninstalled SmartDefrag from 2 PCs running Windows 8.1 (without Fast Startup)
