What is a WSM file?
Installer merge module created with Wise Package Studio, an installer creation utility; stores files and installation settings in a single package, which can be installed on Windows systems.
Files can be added or removed from WSM packages using Wise Package Studio. Once a package has been modified, it must be recompiled into a merge module by Wise Package Studio in order to function correctly.
WSM files are similar to .MSM files, but are used specifically by Wise Package Studio.
NOTE: Symantec discontinued Wise Installation Studio and Wise Installation Express on April 19, 2010.
