Convert DB4 to another file type
To convert DB4 Databases to another format, you need dBASE or other Database software.
Convert a file to DB4
To convert other file formats to the "Legacy Database File" file type, you need software like dBASE or a similar tool.
About DB4 files
The .DB4 file extension has several distinct uses, but it is most commonly associated with dBASE IV, a classic relational database management system. In this context, it stores structured data records, fields, and tables used by xBase-compatible software. Another highly common use is as a structural analysis project database created by SCIA Engineer or IDEA StatiCa, which stores complex 3D modeling and engineering calculations. Occasionally, developers use .DB4 to denote a SQLite version 3 database.
Using .DB4 files today presents significant challenges. If the file is a legacy dBASE IV database, it relies on outdated software architectures and is not natively supported by modern web browsers or operating systems. Structural analysis files from SCIA Engineer are heavily proprietary, strictly locked to costly specialized engineering software, and cannot be easily viewed without an expensive commercial license. These files can easily exceed hundreds of megabytes and are difficult to share with non-engineers.
Because of these restrictions, users frequently need to convert .DB4 files into accessible, universal formats. For database files, the best conversion targets are CSV, SQL, or XML, which allow the data to be queried and integrated into modern systems like MySQL or Excel. For SCIA Engineer files, users typically export to industry-standard CAD/BIM formats like IFC, DWG, or DXF, though proprietary calculation metadata may be lost in the translation.
Many standard online converters fail to process .DB4 files because they are closed, proprietary, or rely on legacy database encoding. Often, only the original software can properly read or export the exact data schema. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your DB4 file, detects the exact format, and lets you read the text inside.
If you want to convert DB4 file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use dBASE or similar software from the "Relational Database Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, MDF, MDB, LDF, DB, DB3, SQLITE or FRM files to DB4, try dBASE or another comparable tool in the "Relational Database Storage" category.
The DB4 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 DB4 converter.
