1. A computer implemented system for predicting a target file directory, comprising:

  • a first component that infers and/or determines expected navigation costs for directory operations associated with potential target directories, the expected navigation cost is based on a probabilistic and/or utility analysis that includes a list scan penalty for reducing probabilities associated with scanning lists within a directory; and

    a second component that outputs a subset of the potential target directories to a display, the subset is determined by selecting target directories, based in part on the expected navigation cost, in order to minimize a cost of traversing directories.
