What is an NCM file?

NCM files mostly belong to Netease Cloud Music. An NCM file is a proprietary encrypted audio file used by Netease Cloud Music. It stores music tracks in an encrypted format to protect the content from unauthorized access.
Usage and Functionality:

The file cannot be played by standard media players because of its encryption.

It is designed to work with the official Netease Cloud Music client.

Conversion to common audio formats like MP3 may be needed for use in other applications.

FilExt.com tip: The file may also contain metadata such as track details and artwork. Its encryption is specific to Netease's system, so using trusted software is important when converting or handling these files.

NCM file format:

To find out what program is needed to open NCM files, you need to determine the file format. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the NCM files is as follows:

The NCM file extension is quite common and mainly uses a special format. But the following two file formats are common:

95% of all NCM files use the same file format, which can be identified by the letters "CTENFDAM" at the beginning. These files are binary files, so they do not contain text, but only cryptic characters. A typical file size is 9 MB. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. CTENFDAM, RUPC and JY/UW%6P4W. Files like these have the following tags: live, love, aimer, summer, walker, seconds, down, beyond, bieber, teeth, feat and chart music.
2% of all NCM files have the same signature #,K 1001. The contents of these files are easily readable with a text editor. NCM files can be up to 3 KB in size, but are often around 1.6 KB - 1.7 KB.
