A portable Windows tool for After Effects presets: converts .ffx files for every AE version after CS5.5 — a verified full downgrade to CS5.5's native format, or native-format effect removal for any newer target — strips effects whose plugins you don't own, and shows exactly what is inside a preset. All offline, in one single exe.
