Configuration

By default, O&O Defrag is configured to work optimally for most users.
The options available in the configuration dialog cover the most common use cases, ensuring that your computer maintains high performance without requiring additional adjustments.

You can access the configuration via the ribbon menu at the top left of the user interface.
If you make any changes, please click OK to apply them.

Automatic Defragmentation - Automatically optimize hard disks
All new or modified files are checked. Fragmented files are automatically defragmented once they have not been written to for a while.
→ Your system remains permanently optimized, and fragmentation is actively prevented.

  • Optimize when the user is away
    Starts defragmentation as soon as the screensaver is active (e.g., during breaks).
    Defragmentation pauses as soon as you return to the computer and will automatically resume later.

  • Defragmentation at scheduled times
    Set up recurring schedules for defragmentation, which will then run automatically.

Additional Automatic Optimizations - SSD Optimization with TRIM
O&O Defrag optimizes SSDs vendor-independently using TRIM commands.
- Frees up no longer needed storage areas
- Faster access times
- Reduced wear on flash memory cells

  • ThinProvisioning for Virtual Machines
    • Faster release and reallocation of storage space
    • Reduced storage requirements
    • Increased performance

ThinProvisioning can be executed regularly, either independently of defragmentation or after each defragmentation process.
