Open ISU File

The ISU file format and extension is primarily used for InstallShield Uninstall Script Format.

The ISU format is basically an uninstall script and is run directly by the InstallShield software installation program.

The ISU extension stores a useful script for uninstalling programs and is based on the InstallShield application.

The ISU file script is created to find and remove files related to a specific program, since it has the paths and records related to those files, thus ensuring their complete removal from the computer.

The ISU format was developed by Flexera Software, also creator of InstallShield Uninstaller Script, hence the initials of the extension, for the InstallShield software series.
