About CF4 files

The .CF4 extension serves two distinct, proprietary purposes that often confuse users.

1. SCT LiveLink Configuration (Primary)

Most commonly, a .CF4 file is a configuration profile for SCT Performance LiveLink Gen-II software. It defines the specific list of parameters (PIDs) and equations a tuner monitors during vehicle diagnostics.

The Problem: These files are locked to the SCT ecosystem. You cannot view the parameter list in Microsoft Excel or standard text editors. Sharing a diagnostic setup with a mechanic who lacks the exact software version often results in compatibility errors.
The Solution: Convert the configuration to PDF to create a fixed, shareable document of your tuning parameters. For tuners needing to migrate data definitions, converting to TXT or CSV allows for manual inspection of the PID structures.

2. Cathy Disk Catalog (Secondary)

Less frequently, a .CF4 file is a media catalog created by the Cathy disk cataloging utility. It stores a searchable index of files from CD/DVDs or hard drives.

The Problem: This is a legacy format. If you want to migrate your disk index to a modern asset manager or simply view your file lists in a spreadsheet, the native application offers limited export options.
The Solution: For this use case, converting the .CF4 catalog to CSV or XLSX is essential for importing your data into modern inventory tools like LibreOffice Calc.

Convert.Guru analyzes your CF4 file, detects the exact format, and lets you read the text inside.
