Fast comparison using multi-level version format

摘要

A system and method to implement a technique to compare a collection of files. A reference index is extracted from a reference version file. The reference index specifies contents of a reference directory at a binary level. A target index is extracted from a target version file. The target index specifies contents of a target directory at the binary level. The target index is compared against the reference index to determine whether the contents of the target directory match the contents of the reference directory.
