Abstract
Disclosed embodiments relate to storing and accessing files. In an embodiment, a method includes writing a file to a writing a file to a storage device having a file system having a file allocation table (FAT). Writing the file includes allocating a plurality of clusters of the file system to the file, wherein at least a portion of the allocated clusters is contiguous. The FAT includes a plurality of cluster addresses corresponding to the allocated clusters. A signature value is stored in a cluster address corresponding to a first cluster of the contiguous clusters to indicate the presence of the contiguous clusters. In each of a set of consecutive cluster addresses succeeding the cluster address corresponding to the first cluster, a value that partially represents the number of the contiguous clusters is stored. The number of contiguous clusters is determinable by combining the values stored in the consecutive cluster addresses.
