WinContig is a lightweight and efficient tool focused on file defragmentation with a customizable approach, but lacks multi-disk support and detailed reporting features. In contrast, MyDefrag offers a more comprehensive solution with disk space analysis and multi-disk support, making it suitable for users needing detailed insights and optimization, although it lacks command line functionality.
