JRE VM Pack Structure

InstallAnywhere 2020

VM packs are stored as archives with a .vm extension. VM packs contain a VM archive (vm.zip or vm.tar.Z) and a vm.properties file.

The structure and contents of the JVM archive inside the VM pack vary between Windows-based, macOS or OS X–based, and UNIX-based systems.

VM Pack Structure for Different Platforms
Platform	VM Pack Structure
Windows VM Packs	Windows.vm \|-vm.properties \|-vm.zip \|-bin \|-java \|-lib
macOS or OS X VM Packs	MAC.vm \|-vm.properties \|-vm.zip \|-jre \|-Contents \|-home \|-bin \|-java \|-lib
UNIX VM Packs	unix.vm \|-vm.properties \|-vm.tar.Z \|-jre \|-bin \|-java \|-lib

Support for VM Packs With Nested JRE Folders

In addition to supporting normal VM pack structure, InstallAnywhere also supports VM packs that have nested JRE folders (such as jre/jre/bin).

The following table lists the VM pack structure for VM packs that have nested JRE folders.
