Abstract
A bit level file comparison system compares two file systems, each of which includes any number of individual files, to determine whether the file systems are identical at a bit level. A hashing function is applied to each file in the first file system to generate a hash value that is logically associated with the respective file in the first file system. The hashing function is applied to each file in the second file system to generate a hash value that is logically associated with the respective file in the second file system. The hash value associated with a file in the first file system is compared with the hash value associated with the corresponding file in the second file system to determine whether bit level differences between the respective file in the first file system and the second file system.
