AviUtl is a video-editing tool for Microsoft Windows created by Japanese developer KEN-kun.
An .aul file stores language settings used to enable a specific language localization in AviUtl.
AviUtl uses .aul files internally for language settings. They are not intended to be opened as documents.
Conversion to other formats is not possible for an .aul file because it stores AviUtl language settings, not a document or media asset.
