Six Updater Suite

Six Updater is a tool to manage Mods, Missions & Servers, for the ArmA2 military simulation by Bohemia Interactive.

Six Updater's main features include MultiThreaded & MultiHost Mods/Missions downloads (installation/updating/repair/migration).
It also deploys delta patching to save time and bandwidth (only downloads changed parts of a file).
Six Updater has a Server Browser with sorting, grouping, search and filtering.
