1. A method for identifying a subset of symbols from a group of symbols that most effectively characterizes a group of files for a plurality of files stored on one or more computing devices, each file of said group of files having a plurality of symbols forming at least a portion of the group of symbols and representing an underlying data stream of original bits of data, the method residing in a non-transitory computer-readable storage medium as executable instructions processed by the one or more computing devices and comprising: determining an amount of information represented by each symbol of said group of symbols by determining a per file amount of information represented by said each symbol of said group of symbols for said group of files, and summing said per file amount of information for said each symbol of said group of symbols for said group of files and ordering said group of symbols based on said summed per file amount of information and selecting a portion of said ordered symbols for use in the calculating, wherein said selected portion of said ordered symbols represents substantially between 80%-99% of a total amount of information within said group of files; and calculating a variance for said each symbol of said group of symbols.
