1. A computer-readable storage medium on which computer-executable instructions are stored which, when executed by a computing device, cause the computing device to:

  • access a directory entry for specifying information concerning data in a file system, the directory entry containing a flag that indicates whether the data is stored in a contiguous cluster chain;

    determine that the data is stored in the contiguous cluster chain based on the flag; and

    identify each cluster in the contiguous cluster chain that stores the data without traversing a file allocation table associated with the file system based on other information within the directory entry and the determination that the data is stored in the contiguous cluster chain, the other information within the directory entry being information specifying a starting cluster and a cluster chain size.
