A method of transforming a data file, the method executed by a processor. The method includes segmenting the data file into data segments and creating a bit index for each data segment having a size that is based on a configurable or preset data group unit. The method then involves indexing each data segment into its corresponding bit index by reading all data group unit values within the data segment and updating the bit index based on the read values, and generating an output data file or files comprising the bit indexes that represent the original data file.
