1. A method for writing files to a tape storage, the method comprising:
identifying a set of files to be written to the tape storage;
retrieving, for each file in the set of files, metadata associated with the file indicating identifiers of users associated with the file;
determining, for each file in the set of files, a predicted frequency metric specifying a predicted frequency of access of the file based on the identifiers of users associated with the file specified in the associated metadata;
sorting files in the set of files to generate a ranked set of files in which each file is ranked relative to the other files in the set of files based on their corresponding predicted frequency metric; and
writing the ranked set of files to the tape storage in descending order of predicted frequency metric such that files having relatively larger predicted frequency metrics are written relatively closer to a starting boundary of a partition of the tape storage.
