What is an NWC file?

NWC files mostly belong to Autodesk Navisworks. NWC files serve two distinct purposes. They are most often used as a Navisworks Cache File for 3D models, but they can also be music notation files for NoteWorthy Composer.

Navisworks Cache File: These files store an aggregated, simplified version of a 3D model. They are generated by Autodesk Navisworks to speed up project loading and review. This cache helps in managing large, complex models in design and construction projects. More details can be found at Autodesk Navisworks.
Music Notation File: In a less common use, some NWC files hold music scores used by NoteWorthy Composer. This variant supports the digital notation process. See information at NoteWorthy Composer.

Opening and Viewing: Open a Navisworks cache file in Autodesk Navisworks for proper viewing and navigation of 3D data. If the file is a music notation file, use NoteWorthy Composer. Note that these files are not meant for direct editing in simple text editors or generic viewers, as they serve specific performance and functionality roles.

How to open an NWC file

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

NWC file format:

If you know the file format, you can also find out how to open or edit the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the NWC files is as follows:

NWC is a very commonly used file extension and predominantly uses a uniform format. However, the following two file formats are common:

75% of all NWC files use the same file format, which have the signature #LcUStream-V1.1. These files contain neither text nor words, but only data. The files are often between 220 KB and 28 MB in size. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. #LcUStream-V1.1 binary double release C lichunk-008. These files are attributed to model, arch, building, central, layout, level, navis and electrical.
25% of all NWC files are Noteworthy Composer data files. They consist of unreadable binary data. The file size is in the range of 810 bytes to 7 KB. The files contain the following words: [NWZ]. These files are attributed to music and song.

How to solve problems with NWC files

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