Help and support

Use F1 for help in the application. If a general help page opens, find the relevant task in this guide's sidebar.

For product assistance, open O&O Defrag support or O&O Software support.

Prepare a useful support request​

Include:

  • O&O Defrag edition and full version/build from About.
  • Windows version and architecture.
  • The affected drive letter, file system, media type, and connection type.
  • The action and method, and whether it was manual, automatic, scheduled, or boot-time.
  • The exact error and approximate time.
  • Steps to reproduce it and what you expected.
  • The relevant report and diagnostic log.

For command-line issues, include the command without private paths or secrets, the output, and the exit code. For jobs, include the relevant schedule and conditions. For Windows RE issues, include preparation details and whether BitLocker was involved.

Collect logs​

Enable logging, reproduce the problem once, and open the log viewer from About. See Reports and logs for the files and recovery-environment paths.

Use engine logging when support requests detailed diagnostics. Return diagnostic settings to your normal level after the investigation.

Protect private information​

Review attachments before sending. File paths, user names, machine names, and licensing information can appear in reports and logs. Share them through the support channel appropriate to the issue and omit full license keys from public discussions.

For questions about a separate tool, identify the tool and its own version as well as the Defrag version used to launch it.
