Are files on a hard drive taking longer to access as they become scattered across the disk? Auslogics Disk Defrag analyzes drives and organizes fragmented HDD files, with options for targeted and scheduled maintenance.
What does drive analysis show?
Choose a drive and run an analysis to see its fragmentation state before starting an operation. Disk Defrag presents the results on a cluster map, giving a visual view of how data occupies the drive. The analysis can guide whether to defragment or optimize.
SSDs are recognized and left out of normal defragmentation, which they don’t need. Its standard defrag workflow is intended for hard disk drives.
Targeted defragmentation and optimization
When a particular game or application has scattered files, Disk Defrag can work on selected files or folders instead of the whole drive. For broader maintenance, its optimization options include handling small files, Prefetch and paging data, and TRIM functionality. It can also consolidate free space, gathering scattered empty areas into a contiguous block.
Scheduled HDD maintenance
A schedule can have Disk Defrag check a hard drive at a chosen time and start defragmentation when it detects that the drive needs it.
The program can also be made portable and saved to a USB drive. That copy can run on another computer, including one without internet access or free space on its system drive.
Pros
- Defragment individual files or folders without processing an entire drive
- Combines scattered free space into a contiguous block
- Can schedule checks and defragmentation for HDDs
- Creates a portable copy for use from a USB drive
System requirements: Windows 7, Windows 8, Windows 8.1, Windows 10, Windows 11 · 32-bit and 64-bit
Can Disk Defrag work on just one folder?
Yes. Select a folder or individual files for defragmentation without processing the entire hard drive.
Does Disk Defrag defragment an SSD?
It detects SSDs and does not run its regular defragmentation on them.
What does a scheduled defrag do?
At the chosen time, the program checks the HDD and automatically defragments files if it finds fragmentation.
