Extract text from Volume files (VOL)
To convert VOL Volumes to another format, you need Kretz VolView or other 3D software.
To convert other file formats to the "Medical Volume Data" file type, you need software like Kretz VolView or a similar tool.
.VOL files are complex, multi-purpose binary files. They primarily store 3D/4D ultrasound volume data captured by GE Healthcare and Kretztechnik clinical systems. Alternatively, they function as compressed game data archives in popular video games like Gran Turismo, World of Tanks, and titles built on the Torque Game Engine.
Opening these files is incredibly frustrating for standard users. Medical .VOL files are proprietary and locked to specific clinical ecosystems. They require specialized clinical software like Kretz VolView or expensive DICOM workstations. The files routinely exceed 100MB and are completely unsupported by standard web browsers, making it difficult for parents to share 3D baby ultrasounds. Similarly, game .VOL archives lock away internal textures, audio, and models. You cannot open them natively in Windows Explorer; they demand game-specific unpacker scripts that are often entirely command-line based.
To make this data usable, conversion is the only pragmatic workaround. For sharing medical ultrasounds with family, convert .VOL to standard video formats like MP4 or images like JPG. To use the 3D data in modeling software, convert it to standard 3D meshes like STL or OBJ. For game modding, extract the archives into standard ZIP files.
Convert.Guru analyzes your VOL file, detects the exact format, and lets you read the text inside.
Users also converted VOL1, VOL2, ZIP, EGG, EXE, JPG, PKPASS, SDOCX and CDB files.
If you want to convert VOL file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use Kretz VolView or similar software from the "3D Volumetric Medical Data" 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 VOL, try Kretz VolView or another comparable tool in the "3D Volumetric Medical Data" 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 VOL converter.
