Get help with FastEditor.

Before contacting support

• Check the documentation for common workflows.
• Restart FastEditor and reopen the affected file.
• Confirm the file encoding and whether the file changed on disk.
• Try the latest available FastEditor build.

Report a bug

Please include the FastEditor version, Windows version, file type, approximate file size, steps to reproduce, expected behavior, and screenshots or logs when possible.

For sensitive files, send a sanitized sample that still reproduces the problem.

Licensing and purchases

For checkout, license delivery, invoice, or activation questions, contact support with the purchase email and order reference. Do not include full payment card details.

Large files and logs

If a file opens in mapped read-only mode, this is expected for very large files. Use it for inspection, search, and navigation while keeping memory usage controlled.

Recovery help

If your session was interrupted, reopen FastEditor and review any restore prompt. Include recovery details when contacting support about unsaved work.
