This is a utility with a graphical user interface and a command line interface that can be used to view and extract the contents of an MSI file.

For usage on the command line: lessmsi [/x <msiFileName> [<outouptDir>]]

Features

Windows Explorer Integration

Lessmsi also integrates with Windows Explorer so that you can right-click on a Windows Installer file (.msi file) and select "Extract Files" to extract it into a folder right there:

Just select Preferences from the Edit menu to enable (or disable) the explorer integration:

GUI

In addition to allowing you to extract files from the command line and from inside Windows Explorer, lessmsi has a graphical user interface that allows you to view detailed information about any MSI file.

MSI Table Viewer

Windows Installer (.msi files) are based on an internal database of tables. Lessmsi features a viewer for those tables. Useful for people who work a lot with installers.
