Systems and methods for managing files in a computer system by segmenting files

摘要

Systems and methods allow for reliably and efficiently managing files stored on a data storage medium associated with a computer system such as a set-top box. In one embodiment a method of managing a file is provided. The method includes: mounting a first file system to a second file system; creating, by the first file system, a virtual file by partitioning a file into a plurality of segments and by linking the plurality of segments in an index file; and sending a file operation request, by the first file system, to the second file system based on the segments of the virtual file.
