This container stores Quick Look preview data for Acorn 8, helping Finder generate previews and thumbnails for Acorn documents on macOS.
What is com.flyingmeat.Acorn8.QLPreview?
~/Library/Containers/com.flyingmeat.Acorn8.QLPreview is a macOS app container used by Acorn 8 for its Quick Look preview extension. Acorn 8 is a native Mac image editor used to open, edit, create, and export images, including its own .acorn document format. The Quick Look component helps Finder show previews and thumbnails for supported files so you can inspect images without fully opening them in the editor. This container can hold extension-specific data and settings that support that preview workflow. Users usually encounter it indirectly when browsing files in Finder, using the space bar for Quick Look, or viewing thumbnails in file lists.

Safety overview
Status: Mostly safe
This folder is associated with Acorn 8's Quick Look extension, which is consistent with Finder preview and thumbnail features on macOS. It is not a system file, but removing it can reset preview-related container data and may temporarily break or delay previews for Acorn documents until macOS or Acorn recreates the folder. If you no longer use Acorn 8, the folder is generally low risk to remove after quitting the app.
Recommendation: Keep this folder if you use Acorn 8 and want Finder previews for Acorn files to work normally. If Acorn 8 has been uninstalled or you no longer open Acorn documents, you can remove it as part of app cleanup; the main effect is losing stored preview-extension data.
