Extract text from One-Step Backup files (1-STEP)
To convert 1-STEP backups to another format, you need Roxio 1-Step Backup or other Backup software.
To convert other file formats to the "Backup Archive Container" file type, you need software like Roxio 1-Step Backup or a similar tool.
The .1-step file format is a proprietary backup archive generated by legacy Roxio 1-Step Backup and related Veritas data protection software. These files bundle user data, directory structures, and system files into a single, compressed container for disaster recovery purposes.
The main disadvantage of the .1-step format is its highly restrictive, closed-source nature. Because the format is proprietary, these files cannot be natively opened by modern operating systems like Windows or macOS. Furthermore, standard archiving utilities such as 7-Zip or WinRAR typically fail to read the internal compression schema. Users are often forced to track down obsolete, paid software to restore their data, which introduces massive friction when trying to recover older backups.
To ensure long-term data accessibility, you should convert or extract .1-step files into standard, open formats like ZIP or TAR. This file format is notoriously difficult to open or convert because often only the original software can properly read or export the internal file table. Standard online converters generally fail to process it. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your 1-STEP file, detects the exact format, and lets you read the text inside.
Users also converted WBCAT, ZC and TZB files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our 1-STEP converter.
