Abstract
Several systems and methods for accessing files stored in a storage device are disclosed. In an embodiment, the method includes accessing a file allocation table (FAT) in a computer file system associated with the storage device. The FAT includes a plurality of cluster addresses corresponding to a plurality of clusters allocated to a file stored in the storage device. A cluster address is read to identify a location of a next cluster. One or more bits in the cluster address are read to determine a presence of a signature value indicating allocation of a set of contiguous clusters from among the plurality of clusters. A number of contiguous clusters is computed based on a pre-determined number of consecutive cluster addresses succeeding the cluster address if the signature value is present. The set of contiguous clusters are read from the storage device based on the computed number of contiguous clusters.
