Extract text from Unity packages (WHIRLD)
To convert WHIRLD packages to another format, you need Unity or other Game software.
To convert other file formats to the "Unity Environment Package" file type, you need software like Unity or a similar tool.
The .WHIRLD file format is a legacy Unity Whirld Package developed by Aubrey Falconer for storing 3D game environments. These files contain comprehensive world data, including terrain meshes, lighting configurations, and player spawn locations. They were primarily utilized alongside the Unity engine and streamed via niche applications like Syn3h.
The main disadvantage of the .WHIRLD format is its highly specialized, proprietary nature. It relies on deprecated third-party libraries, meaning it cannot be opened by standard 3D software or web browsers out of the box. Users typically need to convert these packages into universal 3D formats like FBX, OBJ, or standard UNITYPACKAGE files to salvage the underlying geometry and textures for modern projects. During conversion to generic formats, custom shaders, lighting bakes, and engine-specific physics logic are invariably lost.
Because this format uses closed engine serialization, standard online converters consistently fail to process .WHIRLD files. Often, only the original Unity editor with the specific legacy plugin installed can properly read or export the data. While direct 1:1 conversion of complex game logic is impossible outside of the original engine, our system can identify the file format, inspect the internal package structure, and show raw text configurations. If our analysis detects a supported underlying or embedded format - such as standard mesh data or image textures - viewing or extraction may still be possible.
Convert.Guru analyzes your WHIRLD file, detects the exact format, and lets you read the text inside.
If you want to convert WHIRLD file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use Unity or similar software from the "3D Game Environment Storage" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to WHIRLD, try Unity or another comparable tool in the "3D Game Environment Storage" category.
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 WHIRLD converter.
