What is a GW file

GW files mostly belong to sep reader. A GW file is a specialized document that uses the SEP/SUREXML format to store structured data. It is built on an XML schema so that the file holds clear markers for different data elements. This format is used by the sep reader application for handling and exchanging document content.
Details include:

Format: An XML-based structure that defines data organization.

Usage: It serves as a document file for automated data processing and exchange.

Access: Open it with the sep reader, or view the plain XML using a text editor.

Alternate Name: Also known as a SEP/SUREXML Document File.

FilExt.com note: If you plan to modify the file, ensure the XML remains valid to prevent data loss.

How to open a GW file

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

Programs that open and convert GW files:

sep reader
See the previous paragraphs to learn more about the main application. GW files are often referred to as sep reader simple text files because this type of file is primarily created or used by this software.
Seismic processing and geological modeling software
A .GW file is a specialized data file primarily associated with seismic processing and geological modeling within the energy industry. It typically contains information related to gravity and magnetic surveys, crucial for understanding subsurface structures. These files often store data in a proprietary format optimized for specific geophysical software packages, enabling efficient handling and analysis of large datasets. The content within a .GW file may include gravity or magnetic field measurements, coordinates, survey parameters, and processing information. Due to the complexity and specialized nature of these files, they are primarily handled by dedicated geophysical software and are not intended for direct manipulation by end-users. This file format is classified as Geophysical Data File.

GW format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Below you will find our evaluation of the GW files:

The GW file extension is rarely used and is primarily used by a single program. The two most popular formats are as follows:

70% of all GW files store the data in the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files contain neither text nor words, but only data. The files are 15 KB to 240 KB in size, with a median of 54 KB. This file type is based on cutting-edge technology. The keywords <FileHeader DocType = "SEP2__SUREXML" Version = "1.4.16.12"> <OpenProgram name = "sep reader" version = "1.00" priority = "1"/> <OpenProgram name = "sep viewer" version = "1.00" priority = "2"/> <Open are typical for these files. A usual file name is -2025-.gw.
9% of all GW files are GeneWeb genealogy data files. If you open these files in a text editor, you can view and read the content yourself. The file size is in the range of 6 KB to 430 KB. The files contain the following words: encoding: utf-8, gwplus, end fevt and marr.

All other GW files (21%) have no uniform format. You can get all the details of your GW file by dragging it onto this page or by clicking the button "Choose your .gw file to analyze" above.

How to solve problems with GW files

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