What is a GLOBALCATALOG file?

GLOBALCATALOG files mostly belong to macOS. A *.GLOBALCATALOG file is an index used by macOS Spotlight to quickly locate files and information on the system. It stores metadata about files, such as their name, content, and location, allowing for efficient searching. The internal structure of these files is proprietary and optimized for Spotlight's indexing and retrieval mechanisms. When a user initiates a search in Spotlight, the *.GLOBALCATALOG file is consulted to rapidly identify matching files without needing to scan the entire file system. Changes to files and folders on the system trigger updates to the *.GLOBALCATALOG file to maintain its accuracy and relevance for future searches.
