com.flyingmeat.Acorn8.QLPreview is the Acorn 8 Quick Look extension container used on macOS to store data for Finder preview integration.
What is com.flyingmeat.Acorn8.QLPreview?
com.flyingmeat.Acorn8.QLPreview is a macOS app container for the Quick Look preview extension that works with Acorn 8, an image editor for Mac. Quick Look extensions let Finder generate previews and thumbnails so you can inspect supported files without fully opening them in the main app. This container can hold sandboxed data the extension uses while providing those previews, such as temporary working files, saved state, or other support data managed by macOS. Users usually encounter it only inside the Library folder rather than through a normal app window. If you use Acorn 8 to browse or preview images in Finder, this container helps support that workflow on your Mac.

Safety overview
Status: Mostly safe
This folder belongs to the sandboxed Quick Look component associated with Acorn 8. Its presence is consistent with Finder preview integration on macOS. Removing the container does not uninstall Acorn 8, but it can reset stored extension data and may temporarily affect previews until macOS recreates the folder. If you no longer use Acorn 8, deleting this container is generally low risk after quitting Acorn and Finder-dependent preview activity.
Recommendation: Keep this folder if you still use Acorn 8 or rely on Finder previews for files it handles. If Acorn 8 has been removed from your Mac, you can delete this container as part of cleanup; macOS may recreate it later only if the related extension is used again.
