When a file is classified (e.g., for data management), the classification properties are cached in association with the file, along with classification-related metadata that indicates the state of the file at the time of caching. The classification-related metadata in the alternate data stream is then useable in determining whether the classification properties are valid and up-to-date when next accessed, or whether the file needs to be reclassified. If the properties are valid and up-to-date, they may be used without requiring the computationally costly steps of reclassification. Also described is using more than one alternate data stream for the cache, and extending the classification-related metadata through a defined extension mechanism."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Alternate data stream cache for file classification","description":"Described is caching classification-related metadata for a file in an alternate data stream of that file.
