What is a MODPKG file? A MODPKG file is a package file used by BlockLauncher, an app that allows users to load game modifications into the Minecraft: Pocket Edition game for Android. It contains a modification to gameplay, such as unique blocks, decoration items (tables, TVs, etc.), backpacks, and other textures. MODPKG files are compressed with Zip compression

More Information MODPKG files are designed to allows users to share modifications to Minecraft gameplay and are similar to .JS scripts. Since you cannot load the MODPKG file directly into Minecraft: Pocket Edition you need to use the BlockLauncher app, which wraps around the Minecraft: Pocket Edition game to enable users to load mods, patches, and texture packs into the game. To load a MODPKG file into BlockLauncher: Download the MODPKG file. Tap the wrench icon. Select "Manage ModPE Scripts." Tap Import → Local Storage and navigate to your MODPKG file in the "Downloads" folder. Restart BlockLauncher.
