What is an NDW file?

NDW files mostly belong to Allplan. NDW files are mainly used for computer aided design (CAD) drawings.
They store project designs in formats managed by Nemetschek Allplan.

Primary use: A CAD drawing file created and edited in Allplan.

Alternate use: A notes database file based on the JetDB engine, which some users access with Microsoft Access.

For CAD variants, visit the Allplan website for more details. For the notes database variant, you might refer to the Microsoft Access website.
FilExt.com tip: Open these files with the correct software to view and edit their content.

How to open NDW files

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

Programs that open and convert NDW files:

Allplan
See the previous paragraphs to learn more about the main application. NDW files are often referred to as Allplan cads because this type of file is primarily created or used by this software.
Allplan (Drawing File) by Nemetschek A.G.
Allplan Architecture is a software solution for every phase of the project lifecycle from early freehand sketching through to the construction documentation. Allplan Architecture features practical function, a comprehensive user guide, convenient modification features and a project structure suited to project teams of any size. Usually NDW files are accessed through a specific document/project manager in Allplan witch allows grouping and editing of more than one file in a manner that is not equivalent to the filesystem tree style, but more like a database that can be structured in a more natural way for drafting and design process. The .NDW file itself is used individually mainly for exchange. This file format is classified as CAD/CAM.

NDW file format:

The file format determines how the data is stored in the file. 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. 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. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the NDW files produces the following result:

NDW is rarely used as a file extension and is used by different programs with different formats. The file formats most commonly found in NDW files are:

55% of all NDW files have the same signature 52 02. These files contain neither text nor words, but only data. The file size is in the range of 260 KB to 6 MB. The file type is relatively new. tb20180601.ndw is a typical file name. Such files are related to plan.
35% of all NDW files start with the magic bytes 52 00, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are 98 KB to 2 MB in size, with a median of 550 KB. Examples of file names are tb20180601.ndw.

All other NDW files (10%) have no consistent format, frequently e.g. JetDB. Drag & drop your file here to see the file format and a preview of your NDW file!

How to solve problems with NDW files

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