The Batch Optimize Folder operator runs via a background Blender subprocess — so yes, you can optimize hundreds of files without opening Blender manually.

Yes — check the _backups/ folder next to your .blend file (or the custom backup location you set in preferences). BlendOptimizer saved a copy before touching anything.

Your file was probably already clean 🎉. Run Analyze File first — if orphan count is near zero and no textures are oversized, there isn't much to compress. Try the Resize Oversized Textures operator with a lower target resolution for more aggressive savings.

GPL-2.0-or-later (required for all Blender addons). This doesn't restrict how you use the results — you own everything you produce with it.

Yes. All future 1.x updates are included in your purchase.

Yes, absolutely. Use it on any project — client work, asset packs, game assets, animations, whatever. There are no runtime restrictions.

Depends on the file. Typical results: - Sculpt / photogrammetry scenes: 40–70% smaller - Studio asset files with unused variants: 20–40% smaller - Already-clean files: 5–10% (orphan buildup over time)

No. All operations are non-visual: - Duplicate materials are merged (identical ones only — compared via hash) - Textures resize to the target resolution you choose (default 2048) - Orphans are unused data by definition — removing them can't change your render

Yes. The orphan purge respects linked data (do_linked_ids, do_recursive) and won't break library overrides.

Blender's built-in purge only handles one piece of the puzzle. BlendOptimizer also: - Merges duplicate materials (Material.001, Material.002 → single material) - Resizes oversized textures to your target resolution - Removes unused images from memory (not just orphans) - Cleans empty collections - Batch-processes entire folders of .blend files at once - Gives you a full file analysis with size breakdown

Yes, it's safe. BlendOptimizer automatically creates a timestamped .blend backup before any destructive operation (purging orphans, removing images, resizing textures, etc.). You can disable auto-backup in preferences, but it's on by default. You can also "Dry Run" most operations to preview changes.
