What is an XWM file

XWM files mostly belong to Fallout 4. XWM files are compressed audio files built on the RIFF container format.
This format is used to store sound data for games. The files are encoded with the XWMA audio codec and are the same type of files used in Fallout 4.
Details include:

Format: RIFF-based structure

Function: Compress and store game audio efficiently

Usage: Commonly found in game soundtracks, notably Fallout 4

FilExt.com note: These files are designed for use in game audio environments and require appropriate media players or game audio tools that support the XWMA codec.

How to open an XWM file

File extension, signature and file format must match; otherwise errors will occur when the file is opened.

The XWM file extension is not widely used. Such a file predominantly uses a uniform format.

100% of all XWM files are XWMA audio files, which are using the popular RIFF file format. RIFF files store data in tagged chunks. There are primarily used to store multimedia such as sound and video. The contents of these files cannot be read by a human; only a computer program can interpret the data. XWM files are between 9 KB and 3 MB in size. The file type was developed only in the last few years. The following keywords are characteristic: XWMAfmt, RIFF and dpds. Examples of file names are MUS_MainTheme.xwm or 1.xwm.
