.MSI

📌 .MSI data container is considered as a Windows package which includes installation data for a specific installer, among which are precise installation locations and paths and files themselves to be installed. In common, the .MSI sources can be applied for Windows updates or external third-party software installers. On the composition and structure, the .MSI-based packages are quite identical to .EXE executables. Therefore, both of them are applied to open, preinstall and launch Windows apps and utilities. The essential difference between .MSI and .EXE extensions is that the .MSIs always contain installers, while the .EXE containers do not and may easily execute the program they include after a double-click on the disk entry.
