Extract text from 3D model files (BTO)
To convert BTO 3D models to another format, you need LODGen or other Game software.
To convert other file formats to the "Level-of-Detail Data File" file type, you need software like LODGen or a similar tool.
The .BTO file extension generally functions as a Game Object Level-of-Detail (LOD) Data file used primarily in Bethesda games like Fallout 4 and Skyrim. Generated by modding utilities such as LODGen or DynDOLOD, these files store simplified 3D mesh data for distant objects to improve game performance. A secondary, but common, use for .BTO files is as proprietary HP Factory Installation Scripts used by Hewlett-Packard to configure Windows machines during manufacturing.
Users typically attempt to convert or open .BTO files when troubleshooting game mod installations or trying to analyze pre-installed HP bloatware scripts. However, the current format is highly restrictive. Game LOD files are compiled, proprietary binary data that exceed normal file sizes and cannot be opened by standard text editors or web browsers. HP installation scripts often require special internal setup environments to run properly and offer no direct consumer utility.
Because these are closed, proprietary formats, standard online converters fail to process them. You cannot easily convert a Bethesda .BTO file into a standard OBJ or FBX 3D model without specialized modding tools. If you are dealing with a script, the best conversion targets are plain text formats like TXT or XML to read the code.
This file format is difficult to open because only the original software (the game engine or the HP installer) can properly read or export the data. Despite these limits, convert.guru provides a pragmatic workaround. Just drag and drop your file to identify the format, view its raw hex or internal text content, and convert it when possible. If our analysis detects an embedded plain-text script or supported structural data, viewing and extraction become instantly available.
Convert.Guru analyzes your BTO file, detects the exact format, and lets you read the text inside.
If you want to convert BTO file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use LODGen or similar software from the "Game LOD Data Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to BTO, try LODGen or another comparable tool in the "Game LOD Data 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 BTO converter.
