Opening an LWD File

The LWD file type is primarily associated with LabVIEW.

What is an LWD file?

LWD files mostly belong to LabVIEW. LWD files are used in specialized industries and come in several formats. The largest group is a directional drilling data file. This type, sometimes called a DCI-F5-DLG data file, stores wellbore trajectory and sensor information for drilling operations.

Directional Drilling Data: Contains logs and measurements used to track drilling direction.

Another group of LWD files is the LabVIEW diagram file, which holds block diagrams and wiring information created with National Instruments LabVIEW. These files are also known as LogiKal CAD files. For more details, see the NI website.

LabVIEW Diagram: Stores system design details and diagrammatic representations for data acquisition.

A smaller group are the LiveModel files, used as process model data files in simulation environments such as AllFusion Process Modeler. These files may also be referred to as LogiTerm Wizard Data files. Additional insights are available at the BMC page.

LiveModel Data: Contains data for process simulation and model tracking.

FilExt.com note: Each version demands its own specialized application to open and view the data. Check the source or documentation of your file to decide which program to use.

How to open LWD files

You need a suitable software like LabVIEW to open an LWD 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 LWD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LWD file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert LWD files:

LabVIEW
See the previous paragraphs to learn more about the main application. LWD files are often referred to as LabVIEW data files because this type of file is primarily created or used by this software.
LotusWorks (Text Document) by IBM
This was a Lotus product. Lotus was bought out by IBM.

LWD file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the LWD files comes to the following conclusion:

The LWD file extension is rather rarely used and includes different formats for different programs. The two most popular formats are as follows:

35% of all LWD files are MyWay / WipNav speed cameras data files. These are binary files, so they do not contain words or text. The files are 200 KB to 580 KB in size, with a median of 520 KB. This file type is based on cutting-edge technology. The following keywords are characteristic: LWDB and Ver 1.0. The following filename is common: hazardareas.lwd.
35% of all LWD files start with the bytes DCI-F5-DLG, which are crucial for this file format. They consist of unreadable binary data. LWD files can be up to 15 KB in size, but are often around 2 KB - 11 KB. The keywords DCI-F5-DLG are typical for these files. These files can be linked to falconf, crossing, bore and ridgeview.

All the rest of the LWD files (30%) have different formats, often, for example, RWST. If you want to find out what your LWD file contains, drag and drop it onto this page.

How to solve problems with LWD files

Associate the LWD file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest LWD file format. Search, therefore, e.g. on the manufacturer website after an available LabVIEW update.
To make sure that your LWD file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
