What is an ARPROJPKG file? An ARPROJPKG file is a project package created by Spark AR Studio, an augmented reality (AR) effects application that integrates with Facebook and Instagram. It contains a Zip-compressed version of a Spark AR project, including the project's .ARPROJ file and included assets. ARPROJPKG files are used to share AR Studio projects with other users.

More Information Spark AR Studio allows Facebook users to create AR effects that they can apply to Facebook and Instagram videos. For example, a Spark AR Studio user could create a "bubbles" effect and then apply the effect to add AR bubbles to a video. When a user saves a Spark AR Studio project, the program creates a new project directory. This directory contains an ARPROJ file and any assets the user has imported into their project. If a user wants to share their Spark AR Studio project with another user, they can do so by packaging all these files as a single ARPROJPKG file. Packaging a project zips its ARPROJ and asset files into one compressed file that can be shared over the Internet more easily. Sharing a project as a package also prevents users from accidentally not providing the project's assets. To package a project as an ARPROJPKG file, users select File → Package... from AR Studio's menu.
