The Picasa movie project file is a legacy metadata format developed by Google for the Picasa digital photo management software. It primarily stores instructions for compiling multimedia slideshows, including references to source images, audio tracks, and specific transition effects. As a non-executable structure, the format is considered safe for local storage, though it became largely obsolete after Google discontinued the Picasa suite in 2016 in favor of current cloud-based photo management services.
