Disk Defragmentation

Defraggler

Defragment exactly what you want

Most defrag tools only allow you to defrag an entire drive. Defraggler lets you specify one or more files, folders, or the whole drive to defragment.  More...

Safe and Secure

When Defraggler reads or writes a file, it uses the exact same techniques that Windows uses. Using Defraggler is just as safe for your files as using Windows.  More...

Compact and portable

Defraggler's tough on your files – and light on your system.  More...

Interactive drive map

At a glance, you can see how fragmented your hard drive is. Defraggler's drive map shows you blocks that are empty, not fragmented, or needing defragmentation.  More...

Quick Defrag

Give your hard drive a quick touch-up with Quick Defrag.  More...

Defragment free space

Organizes empty disk space to further prevent fragmentation.  More...

Scheduled defragmentation

Defragment while you sleep - and wake up with a faster PC. Set Defraggler to run daily, weekly or monthly.  More...

Multi-lingual support

No matter what your native tongue is, Defraggler speaks your language. It currently supports 37 languages.  More...
