What is an NMD file?

NMD files mostly belong to Hikvision Network Media Player. NMD files are used in two distinct ways.

Network Video Metadata/Network Media Device Files: These files store configuration and metadata information for network-based video systems. They hold details such as recording settings, timestamps, and device parameters. Systems from companies like HDN2 and Hikvision use these files. For example, the Hikvision Network Media Player relies on these files to manage video data. See more information at Hikvision.

Nomads Mod Files: In some cases, NMD files are game mod packages used by the Spring Engine. These files typically use a ZIP format internally to compress game modifications and legacy data, helping players enhance or alter game content. More details are available at SpringRTS.

FilExt.com tip: Each version is accessed with specific software: vendor players for network metadata and, potentially, ZIP tools or game mod managers for the Nomads mod files.

How to open an NMD file

You need a suitable software like Hikvision Network Media Player to open an NMD 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 NMD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NMD file directly in the browser:.

NMD file format:

To view or edit NMD files you need to know the file format, because it determines how the data in this file is stored. The file format can be deduced from the file extension and the signature. 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. Below you will find our evaluation of the NMD files:

NMD is rarely used as a file extension and includes many different file formats. The two most common formats are as follows:

• 10% of all NMD files start with the magic bytes 00 00 00 00 01 00 00 00 02, which are always the first bytes of this file format. The files are 5 MB to 77 MB in size, with a median of 22 MB.
• 10% of all NMD files start with the bytes HDN2Ver , which are crucial for this file format. These are binary files, so they do not contain words or text. The file size is in the range of 70 MB to 310 MB. Certain words are almost always found in the files, such as 4520-1CH-01 and HDN2Ver 4.0.

All other NMD files (80%) have no consistent format, frequently e.g. ZIP and HFR. These files sometimes refer to nomads or acdc. If you want to find out what your NMD file contains, drag and drop it onto this page.
