About OR4 files

The .OR4 file extension belongs to legacy personal information manager (PIM) databases, most notably used by IBM Lotus Organizer 97 GS and In-Mind Organizer. These files store personal schedules, address books, to-do lists, and diary entries in a proprietary, highly structured relational format. The primary disadvantage of the .OR4 format is extreme obsolescence. Because it is a closed-source binary file type from the late 1990s, no modern operating system, web browser, or current calendar application can natively read it. It completely isolates historical data, forcing users to rely on outdated, unsupported software or virtual machines to access their own legacy contacts. To make this data useful again, users must convert these files to standard targets like CSV for databases, VCF for modern address books, or ICS for calendar events. During this process, proprietary layout settings, category colors, and specific relational links between tasks and contacts are usually lost. Because this file format is an undocumented container, it is notoriously difficult to open or convert. Standard online converters fail entirely because they lack the specific database engine needed to parse the records. Often, only the original IBM software can properly read or export the data. However, convert.guru provides a pragmatic workaround. Just drag and drop your file to identify the format, view it, and convert it when possible. Even if full structural conversion is unsupported, our analysis can inspect the file and show raw internal text, helping you recover embedded names, phone numbers, and notes.

Convert.Guru analyzes your OR4 file, detects the exact format, and lets you read the text inside.

Users also converted OR3, OR2 and OR6 files.

The OR4 Converter Story

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 OR4 converter.
