Opening BSW Files

The BSW file type is primarily associated with Cary WinUV.

What is a BSW file

BSW files mostly belong to Cary WinUV. BSW files serve different purposes depending on their origin. The majority of these files are Varian UV-Vis-NIR data files. They store spectroscopic measurements from instruments using Cary WinUV software. These files hold data like absorbance and wavelength values used in chemical analysis.
Another group is used for 3D modeling. In these cases, BSW files act as StruWalker 3D models or Tekla Structures model files and contain geometric and design information intended for building design and construction.
A small fraction are created with .NET as game data files, often known as BlindWrite Split Image, used to store game-related assets.

Spectroscopic data: Managed by Cary WinUV for analytical recordings.

3D model data: Processed via Tekla Structures or StruCad3D for structural design.

Game data: Handled in .NET environments for game asset storage.

FilExt.com tip: For more specialized details on the spectroscopic data, visit Agilent and for the structural modeling, check out Tekla.

How can I open a BSW file?

You need a suitable software like Cary WinUV to open a BSW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your BSW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BSW file directly in the browser:. Just drag the file onto this browser window and drop it.

BSW format details:

A file format defines how the data in the file is structured. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the BSW files:

The file type with the extension 'BSW' includes different formats for different programs. The file formats most commonly found in BSW files are:

• 60% of all BSW files have the same signature 11 56 61 72 69 61 6E 20 55 56 2D 56 49 53 2D 4E. The content consists of binary data as well as text and words. BSW files can be up to 1 MB in size, but are often around 59 KB - 280 KB. The file type is old but is used even today. The keywords Varian UV-VIS-NIR, TContinuumStore and nacSd are typical for these files. Files like these are sometimes connected to data and graph.
• 25% of all BSW files use the same file format, which have the signature 03 00 00 00. They consist of unreadable binary data. A typical file size is 990 KB. The files contain the following words: Layer, nullA, PHASE, USER and nullO.

All other BSW files (15%) have different formats, the following 3 formats exist: .NET. Just click the "Choose your .bsw file to analyze" button on this page to find out what your BSW file is.
