Defraggler is a powerful disk defragmenter made by Piriform for Windows which uses an mild nagware model (it tries to install Chrome by default during installation). It has many features above and beyond Microsoft's Disk Defragmenter that comes with Windows. The features of Defraggler include:
- Full drive analysis and defragmentation.
- List of fragmented files, and the ability to defrag files individually.
- Options for moving large files or specific file types to the end of the drive.
- Quick defragment with custom rules.
- Custom file exclusion filter.
- General drive health and errors.
- Customizable interface that displays the defragmentation progress.
