Extract text from Siebel configuration files (IFB)
To convert IFB configuration files to another format, you need Microsoft Outlook or other Data software.
To convert other file formats to the "Calendar Data & Backup" file type, you need software like Microsoft Outlook or a similar tool.
The .IFB file primarily stores iCalendar free/busy information formatted according to RFC 5545. This plain text format allows servers and calendar clients like Microsoft Outlook to share availability schedules without revealing specific event details. Alternatively, it serves as a system configuration backup file for Ikusi Flow Headend television systems.
The free/busy .IFB format is highly specific and intentionally lacks full event data. Users often receive these files and find them devoid of readable context. It is not natively supported by web browsers, and opening it in standard text editors displays raw, unformatted syntax. The Ikusi Flow variant is even more restrictive. It is a proprietary binary dump that cannot be read or manipulated outside its specific hardware ecosystem.
For the calendar variant, converting .IFB to ICS, CSV, or TXT is the most practical step for integration into modern scheduling tools. However, you must remember that the underlying event details were never in the file to begin with, so conversion will not magically reveal missing meeting names or locations.
Because this extension is shared by both a strict machine-readable calendar syntax and a closed, proprietary binary backup, it is notoriously difficult to open or convert correctly. Standard online converters frequently fail to process it because they cannot parse the dual nature of the extension. Just drag and drop your file onto convert.guru to identify the exact format, view its contents, and convert it when possible. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your IFB file, detects the exact format, and lets you read the text inside.

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 IFB converter.
