The file system provides an operation that allows an extent from one file to be copied into an extent of another file, or into a different extent in the same file if the extents do not overlap. To support such an operation, the file system tracks the storage locations for stored data for extents of a file, and whether the stored data for an extent of a file is shared with any other file or by another portion of the same file. When stored data is shared, writing to an extent of a file that refers to the shared stored data invokes a write operation to a new extent on the storage device, and the tracked information for the affected extents is updated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"File system with data block sharing","description":"To provide an operation that can quickly copy or rearrange a file, a file system allows stored data to be shared among two or more files or within a file.
