Files that contain the .swm file extension are most commonly associated with the ImageX command line application.
The ImageX command line application is used to create Windows disk images. These disk images are saved in the WIM file format. The WIM file format was developed by Microsoft and was used to deploy Windows operating systems, versions Vista and later.
Sometimes the WIM file would need to be split into smaller volumes. When a WIM file is split into separate volumes, the split volumes are given the .swm file extension.
The Supportworks software application also uses the .swm file suffix. These SWM files contain ESP message files that are used by the software program.
