Our verdict: Auslogics Disk Defrag gives HDD owners more control than the Windows optimiser: single files and folders, free-space consolidation, schedules and a cluster map. It is pointless on SSDs, which it detects and skips, and the app promotes its paid Pro edition and other Auslogics tools.
About Auslogics Disk Defrag
Auslogics Disk Defrag is a defragmenter made specifically for hard disk drives. It analyses drives, shows fragmentation on a cluster map, and puts fragmented files back together. It can also consolidate free space so new files are less likely to fragment.
The free edition is free for home and commercial use. It can defragment single files or folders, run scheduled defrags only when needed, and create a portable copy for a USB drive. SSDs are detected and not defragmented; Auslogics sells a separate SSD Optimizer for those. Pro and Ultimate editions add more options.
What it does well
- HDD defragmentation. Reassembles fragmented files on hard disk drives.
- Free-space consolidation. Merges scattered free space into contiguous blocks.
- File and folder defrag. Defragments only selected files, such as a game folder.
- Scheduler. Checks fragmentation at set times and defrags only when needed.
- Portable mode. Creates a portable version to run from a USB drive.
Who it is for
Good fit
PCs with mechanical hard drives, especially older computers and large game libraries.
Look elsewhere
Computers with only SSDs, which do not need defragmentation.
