On peer-to-peer networks (e.g., The Pirate Bay, eMule, or French trackers like YggTorrent), uploaders often name files with extra descriptive text. A user sharing a collection of French postal code maps might label the archive: [FR] Code Postal 590 - Nouveau Dossier.rar . A non-French search engine might misinterpret Nouveau Dossier (French for "New Folder") as the literal English words, leading to the mixed-language Code Postal New Folder 590.rar .
